Design of a Web-Based Decision Support System for Service Portfolios in Heterogeneous Radio Access Network Environments

Newly emerging radio access technologies have produced a novel heterogeneous network environment. Wireless service operators should build the best service portfolio strategy for each user by focusing on the co-existence of multiple access networks and complex service combinations, while maximizing the overall network utilization. Web-based Decision Support System (web-based DSS) is one of the best ways of making service portfolios available to every user in a multiple access network environment. Service designers, customer relationship managers, and network engineers can build the best match relationship between services and networks to enhance user utilization. In addition, the easily accessible web-based DSS in an optimal heterogeneous network operation framework provides opportunities for designing new services. The network load and financial effect of newly designed services could also be analyzed and reshaped easily by testing the DSS functionality. Various mathematical tools have been developed for DSS to integrate different network domains. To demonstrate its applicability to the integration of network domains, we tested various service scenarios in a heterogeneous network environment and evaluated the versatile functions of web-based DSS.

COLLECT: COLLaborativE ConText-aware service oriented architecture for intelligent decision-making in the Internet of Things

Internet of Things (IoT) has radically transformed the world; currently, every device can be connected to the Internet and provide valuable information for decision-making. In spite of the fast evolution of technologies accompanying the grow of IoT, we are still faced with the challenge of providing a service oriented architecture, which facilitates the inclusion of data coming together from several IoT devices, data delivery among a system's agents, real-time data processing and service provision to users. Furthermore, context-aware data processing and architectures still pose a challenge, in spite of being key requirements in order to get stronger IoT architectures. To face this challenge, we propose a COLLaborative ConText Aware Service Oriented Architecture (COLLECT), which facilitates both the integration of IoT heterogeneous domain context data — through the use of a light message broker — and easy data delivery among several agents and collaborative participants in the system — making use of an enterprise service bus —. In addition, this architecture provides real-time data processing thanks to the use of a complex event processing engine as well as services and intelligent decision-making procedures to users according to the needs of the domain in question. As a result, COLLECT has a great impact on context-aware decentralized and collaborative reasoning for IoT, promoting context-aware intelligent decision making in such scope. Since context-awareness is key for a wide range of recommender and intelligent systems, the presented novel solution improves decision making in a large number of fields where such systems require to promptly process a variety of ubiquitous collaborative and context-aware data.     

On bounds of response time performance achievable by multiclass single-server queues

MulticlassM/G/1 systems in steady-state with work-conserving scheduling strategies are studied. Restricting a system's scheduling strategy to making no direct use of the required service times, every time the server becomes idle its memory is cleared, and service may only be interrupted by newly arriving customers, a conservation law is developed by means of inequalities. The conservation law states that if a response time vector composed of the expected response times of the different classes of a system in steady-state is achievable, then it must belong to a well-defined convex polytope (a set bounded by hyperplanes). Furthermore, on each hyperplane bounding the relevant polytope there lies at least one vertex of the convex set of achievable response time vectors. Therefore, this polytope is the least one including the set of all achievable response time vectors.

Game theoretic decision making in IoT-assisted activity monitoring of defence personnel

Innovative growth of IoT Technology has enhanced the service delivery aspects of defence sector in terms of high-tech surveillance, and reliable defence mechanisms. Along with the sensing capability for ubiquitous events, IoT Technology provides means to deliver services in time sensitive and information intensive manner. In this paper, a framework for IoT based activity monitoring of defence personnel is presented to detect the precursors of suspiciousness in terms of information outflow that can compromise the national security. Though maintaining intellectual defence personnel remained a major area of concern for every nation, still investigating reports of recent terrorist attacks in different countries have discovered the number of suspicion factors from their daily activities. The work presented in this study focuses on these factors in terms of efficient monitoring of social activities and analyzing it over suspicious scale. Moreover, Suspicious Index (SI) is defined for every personnel on the basis of their activities that can compromise national security directly or indirectly. Furthermore, automated game theoretic decision making model is presented to aid the monitoring officials in suppressing the probability of information outflow. In order to validate the system, two types of evaluations are performed. In one case, an imitative environment is considered to monitor 10 college students’ daily engagements for 7 days. The results are compared with the state-of-the-art techniques of data assessment. In the second case, a mathematical evaluation for the game theoretic decision making is performed. Results in both cases show that the proposed model achieves better performance in efficient monitoring of suspicious activities and effective decision making.     

自适应文件传输与策略研究

针对目前网络中存在多种数据传输协议,并且各个协议不能或不能很好地兼容其他协议的现状,提出了将文件与文件传输协议进行分离的思想,提出了支持多协议的自适应文件传输的体系结构,提出了针对非局域网的三种文件传输策略：对于大文件依据文件类型采用冗余校验传输或者分片并行传输的策略,对于普通文件采用基于平均服务质量的传输策略,对于小文件采用通道复用的传输策略,而由于局域网的文件传输速率比较高,对于所有文件采用基于平均服务质量的传输策略。在此基础上,提出了自适应文件传输算法AFTA。实验证明其可以依据文件属性等因素,从协议库中选择合适的协议来传输文件,从而有效提高了文件传输的灵活性、高效性,同时保证了可靠性。
