Peer-to-peer grid computing is an attractive computing paradigm for high throughput applications. However, both volatility
due to the autonomy of volunteers (i.e., resource providers) and the heterogeneous properties of volunteers are challenging
problems in the scheduling procedure. Therefore, it is necessary to develop a scheduling mechanism that adapts to a dynamic
peer-to-peer grid computing environment. In this paper, we propose a Mobile Agent based Adaptive Group Scheduling Mechanism
(MAAGSM). The MAAGSM classifies and constructs volunteer groups to perform a scheduling mechanism according to the properties
of volunteers such as volunteer autonomy failures, volunteer availability, and volunteering service time. In addition, the
MAAGSM exploits a mobile agent technology to adaptively conduct various scheduling, fault tolerance, and replication algorithms
suitable for each volunteer group. Furthermore, we demonstrate that the MAAGSM improves performance by evaluating the scheduling
mechanism in Korea@Home.

This paper presents an in-pipe robot, called MRINSPECT V (Multifunctional Robotic crawler for In-pipe inSPECTion V), which is under development for the inspection of pipelines with a nominal 8-inch inside diameter. To travel freely in every
pipeline element, the robot adopts a differential driving mechanism that we have developed. Furthermore, by introducing clutches
in transmitting driving power to the wheels, MRINSPECT V is able to select the suitable driving method according to the shape
of the pipeline and save the energy to drive in pipelines. In this paper, the critical points in the design and construction
of the proposed robot are described with the preliminary results that yield good mobility and increased efficiency.

Many algorithms in distributed systems assume that the size of a single message depends on the number of processors. In this paper, we assume in contrast that messages consist of a single bit. Our main goal is to explore how the one-bit translation of unbounded message algorithms can be sped up by pipelining. We consider two problems. The first is routing between two processors in an arbitrary network and in some special networks (ring, grid, hypercube). The second problem is coloring a synchronous ring with three colors. The routing problem is a very basic subroutine in many distributed algorithms; the three coloring problem demonstrates that pipelining is not always useful.

This paper aims at constructing a music composition system that composes music by the interaction between human and a computer.
Even users without special musical knowledge can compose 16-bar musical works with one melody part and some backing parts
using this system. The interactive Genetic Algorithm is introduced to music composition so that users’ feeling toward music
is reflected in the composed music. One chromosome corresponds to 4-bar musical work information. Users participate in music
composition by evaluating composed works after GA operators such as crossover, mutation, virus infection are applied to chromosomes
based on the evaluation results. From the experimental results, it is found that the users’ evaluation values become high
over the progress of generations. That is, the system can compose 16-bar musical works reflecting users’ feeling.

Information service plays a key role in grid system, handles resource discovery and management process. Employing existing
information service architectures suffers from poor scalability, long search response time, and large traffic overhead. In
this paper, we propose a service club mechanism, called S-Club, for efficient service discovery. In S-Club, an overlay based
on existing Grid Information Service (GIS) mesh network of CROWN is built, so that GISs are organized as service clubs. Each
club serves for a certain type of service while each GIS may join one or more clubs. S-Club is adopted in our CROWN Grid and
the performance of S-Club is evaluated by comprehensive simulations. The results show that S-Club scheme significantly improves
search performance and outperforms existing approaches.

Advances in wireless and mobile computing environments allow a mobile user to access a wide range of applications. For example,
mobile users may want to retrieve data about unfamiliar places or local life styles related to their location. These queries
are called location-dependent queries. Furthermore, a mobile user may be interested in getting the query results repeatedly,
which is called location-dependent continuous querying. This continuous query emanating from a mobile user may retrieve information
from a single-zone (single-ZQ) or from multiple neighbouring zones (multiple-ZQ). We consider the problem of handling location-dependent
continuous queries with the main emphasis on reducing communication costs and making sure that the user gets correct current-query
result. The key contributions of this paper include: (1) Proposing a hierarchical database framework (tree architecture and
supporting continuous query algorithm) for handling location-dependent continuous queries. (2) Analysing the flexibility of
this framework for handling queries related to single-ZQ or multiple-ZQ and propose intelligent selective placement of location-dependent
databases. (3) Proposing an intelligent selective replication algorithm to facilitate time- and space-efficient processing
of location-dependent continuous queries retrieving single-ZQ information. (4) Demonstrating, using simulation, the significance
of our intelligent selective placement and selective replication model in terms of communication cost and storage constraints,
considering various types of queries.

Much recent research has focused on applying Autonomic Computing principles to achieve constrained self-management in adaptive
systems, through self-monitoring and analysis, strategy planning, and self adjustment. However, in a highly distributed system,
just monitoring current operation and context is a complex and largely unsolved problem domain. This difficulty is particularly
evident in the areas of network management, pervasive computing, and autonomic communications. This paper presents a model
for the filtered dissemination of semantically enriched knowledge over a large loosely coupled network of distributed heterogeneous
autonomic agents, removing the need to bind explicitly to all of the potential sources of that knowledge. This paper presents
an implementation of such a knowledge delivery service, which enables the efficient routing of distributed heterogeneous knowledge
to, and only to, nodes that have expressed an interest in that knowledge. This gathered knowledge can then be used as the
operational or context information needed to analyze to the system's behavior as part of an autonomic control loop. As a case
study this paper focuses on contextual knowledge distribution for autonomic network management. A comparative evaluation of
the performance of the knowledge delivery service is also provided.

It is likely that customers issue requests based on out-of-date information in e-commerce application systems. Hence, the
transaction failure rates would increase greatly. In this paper, we present a preference update model to address this problem.
A preference update is an extended SQL update statement where a user can request the desired number of target data items by
specifying multiple preferences. Moreover, the preference update allows easy extraction of criteria from a set of concurrent
requests and, hence, optimal decisions for the data assignments can be made. We propose a group evaluation strategy for preference
update processing in a multidatabase environment. The experimental results show that the group evaluation can effectively
increase the customer satisfaction level with acceptable cost.

PAN is a general purpose, portable environment for executing logic programs in parallel. It combines a flexible, distributed
architecture which is resilient to software and platform evolution with facilities for automatically extracting and exploiting
AND and OR parallelism in ordinary Prolog programs. PAN incorporates a range of compile-time and run-time techniques to deliver
the performance benefits of parallel execution while rertaining sequential execution semantics. Several examples illustrate
the efficiency of the controls that facilitate the execution of logic programs in a distributed manner and identify the class
of applications that benefit from distributed platforms like PAN.

We have developed a high-throughput, compact network switch (the RHiNET-2/SW) for a distributed parallel computing system.
Eight pairs of 800-Mbit/s×12-channel optical interconnection modules and a CMOS ASIC switch are integrated on a compact circuit
board. To realize high-throughput (64 Gbit/s) and low-latency network, the SW-LSI has a customized high-speed LVDS I/O interface,
and a high-speed internal SRAM memory in a 784-pin BGA one-chip package. We have also developed device implementation technologies
to overcome the electrical problems (loss and crosstalk) caused by such high integration. The RHiNET-2/SW system enables high-performance
parallel processing in a distributed computing environment.

This paper investigates the interactions between agents representing grid users and the providers of grid resources to maximize
the aggregate utilities of all grid users in computational grid. It proposes a price-based resource allocation model to achieve
maximized utility of grid users and providers in computational grid. Existing distributed resource allocation schemes assume
the resource provider to be capable of measuring user’s resource demand, calculating and communicating price, none of which
actually exists in reality. This paper addresses these challenges as follows. First, the grid user utility is defined as a
function of the grid user’s the resource units allocated. We formalize resource allocation using nonlinear optimization theory,
which incorporates both grid resource capacity constraint and the job complete times. An optimal solution maximizes the aggregate
utilities of all grid users. Second, this paper proposes a new optimization-based grid resource pricing algorithm for allocating
resources to grid users while maximizing the revenue of grid providers. Simulation results show that our proposed algorithm
is more efficient than compared allocation scheme.

New fusion predictors for linear dynamic systems with different types of observations are proposed. The fusion predictors
are formed by summation of the local Kalman filters/predictors with matrix weights depending only on time instants. The relationship
between fusion predictors is established. Then, the accuracy and computational efficiency of the fusion predictors are demonstrated
on the first-order Markov process and the GMTI model with multisensor environment.

Summary An iteration system is a set of assignment statements whose computation proceeds in steps: at each step, an arbitrary subset of the statements is executed in parallel. The set of statements thus executed may differ at each step; however, it is required that each statement is executed infinitely often along the computation. The convergence of such systems (to a fixed point) is typically verified by showing that the value of a given variant function is decreased by each step that causes a state change. Such a proof requires an exponential number of cases (in the number of assignment statements) to be considered. In this paper, we present alternative methods for verifying the convergence of iteration systems. In most of these methods, upto a linear number of cases need to be considered.

We have developed a real-time gesture recognition system whose models can be taught by only one instruction. Therefore the
system can adapt to new gesture performer quickly but it can not raise the recognition rates even if we teach gestures many
times. That is because the system could not utilize all the teaching data. In order to cope with the problem, averages of
teaching data are calculated. First, the best frame correspondence of the teaching data and the model is obtained by Continuous
DP. Next the averages and variations are calculated for each frame of the model. We show the effectiveness of our method in
the experiments.

This paper presents a sliding mode control method for wheeled mobile robots. Because of the nonlinear and nonholonomic properties,
it is difficult to establish an appropriate model of the mobile robot system for trajectory tracking. A robust control law
which is called sliding mode control is proposed for asymptotically stabilizing the mobile robot to a desired trajectory.
The posture of the mobile robot (including the position and heading direction) is presented and the kinematics equations are
established in the two-dimensional coordinates. According to the kinematics equations, the controller is designed to find
an acceptable control law so that the tracking error will approximate 0 as the time approaches infinity with an initial error.
The RFID sensor space is used to estimate the real posture of the mobile robot. Simulation and experiment demonstrate the
efficacy of the proposed system for robust tracking of mobile robots.

Provisioning QoS guarantee by multipath routing and reservation in Ad hoc networks 总被引:5,自引:2,他引:3 下载免费PDF全文
In this paper, a QoS multipath source routing protocol (QoS-MSR) is proposed for ad hoc networks. It can collect QoS information through route discovery mechanism of multipath source routing (MSR) and establish QoS route with reserved bandwidth. In order to reserve bandwidth efficiently, a bandwidth reservation approach called the multipath bandwidth splitting reservation (MBSR) is presented, under which the overall bandwidth request is split into several smaller bandwidth requests among multiple paths. In simulations, the anthors introduce Insignia, an in-bind signaling system that supports QoS in ad hoc networks, and extend it to multipath Insignia (M-Insignia) with QoS-MSR and MBSR. The results show that QoS-MSR routing protocol with the MBSR algorithm can improve the call admission ratio of QoS traffic, the packet delivery ratio, and the end-to-end delay of both best-effort traffic and QoS traffic. Therefore, QoS-MSR with MBSR is an efficient mechanism that supports QoS for ad hoc networks. 相似文献

Data mining can dig out valuable information from databases to assist a business in approaching knowledge discovery and improving
business intelligence. Database stores large structured data. The amount of data increases due to the advanced database technology
and extensive use of information systems. Despite the price drop of storage devices, it is still important to develop efficient
techniques for database compression. This paper develops a database compression method by eliminating redundant data, which
often exist in transaction database. The proposed approach uses a data mining structure to extract association rules from
a database. Redundant data will then be replaced by means of compression rules. A heuristic method is designed to resolve
the conflicts of the compression rules. To prove its efficiency and effectiveness, the proposed approach is compared with
two other database compression methods.
