A major problem in empirical software engineering is to determine or ensure comparability across multiple sources of empirical
data. This paper summarizes experiences in developing and applying a software engineering technology testbed. The testbed
was designed to ensure comparability of empirical data used to evaluate alternative software engineering technologies, and
to accelerate the technology maturation and transition into project use. The requirements for such software engineering technology
testbeds include not only the specifications and code, but also the package of instrumentation, scenario drivers, seeded defects,
experimentation guidelines, and comparative effort and defect data needed to facilitate technology evaluation experiments.
The requirements and architecture to build a particular software engineering technology testbed to help NASA evaluate its
investments in software dependability research and technology have been developed and applied to evaluate a wide range of
technologies. The technologies evaluated came from the fields of architecture, testing, state-model checking, and operational
envelopes. This paper will present for the first time the requirements and architecture of the software engineering technology
testbed. The results of the technology evaluations will be analyzed from a point of view of how researchers benefitted from
using the SETT. The researchers just reported how their technology performed in their original findings. The testbed evaluation
showed (1) that certain technologies were complementary and cost-effective to apply; (2) that the testbed was cost-effective
to use by researchers within a well-specified domain of applicability; (3) that collaboration in testbed use by researchers
and the practitioners resulted comparable empirical data and in actions to accelerate technology maturity and transition into
project use, as shown in the AcmeStudio evaluation; and (4) that the software engineering technology testbed’s requirements
and architecture were suitable for evaluating technologies and accelerating their maturation and transition into project use.

There is a chronic lack of shared application domains to test advanced research models and agent negotiation architectures in Multiagent Systems. In this paper we introduce a friendly testbed for that purpose. The testbed is based on The Diplomacy Game where negotiation and the relationships between players play an essential role. The testbed profits from the existence of a large community of human players that know the game and can easily provide data for experiments. We explain the infrastructure in the paper and make it freely available to the AI community. 相似文献

Opportunistic routing is a candidate for multihop wireless routing where the network topology and radio channels vary rapidly. However, there are not many opportunistic routing algorithms that can be implemented in a real multihop wireless network while exploiting the node mobility. It motivates us to implement an opportunistic routing, random basketball routing (BR), in a real multi-robot network to see if it can enhance the capacity of the multihop network as mobility increases. For implementation purposes, we added some features, such as destination RSSI measuring, a loop-free procedure and distributed relay probability updating, to the original BR. We carried out the experiments on a real multi-robot network and compared BR with AODV combined with CSMA/CA (routing + MAC protocol). We considered both static and dynamic scenarios. Our experiments are encouraging in that BR outperforms AODV + CSMA/CA, particularly in dynamic cases; the throughput of BR is 6.6 times higher than that of AODV + CSMA/CA. BR with dynamic networks shows 1.4 times higher throughput performance than BR with static networks. We investigate the performance of BR in the large-scale network using NS-2 simulation. We verify the effect of node density, speed, destination beacon signal and loop-free procedure. According to the large-scale simulation, the end-to-end throughput grows with the node speed. 相似文献

Recent developments in the area of decentralized and infrastructureless systems opened avenues for novel applications. Along with these new technologies, new questions regarding their operational bounds in terms of e.g. scalability and security arose. Due to the sparse presence of real-world decentralized and infrastructureless systems, new protocols and applications have to be scrutinized by means of simulation, in (small-scale) testbeds, and by analytical models. In this paper, we discuss challenges of evaluating security mechanisms for mobile ad hoc networks and peer-to-peer systems. We focus on harmonizing predictions of analytical models and results obtained from simulation studies and testbed experiments. 相似文献

The choice of the transmission power levels adopted in Wireless Sensor Networks (WSNs) is critical to determine the performance of the network itself in terms of energy efficiency, connectivity and spatial reuse, since it has direct impact on the physical network topology.In this paper, a cooperative, lightweight and fully distributed approach is introduced to adaptively tune the transmission power of sensors in order to match local connectivity constraints. To accurately evaluate the topology control solution, a small-scale testbed based on MicaZ sensor nodes is deployed in indoor and outdoor scenarios. Practical measures on local and multi-hop connectivity, convergence time and emitted power are used to compare the proposed approach against previous solutions. Moreover, mathematical programming formulations of the topology (power) control problem are introduced to assess the optimality of the distributed algorithm. Finally, simulation analysis complements the experimental evaluation in large-scale static and mobile WSN scenarios, where a testbed implementation becomes unfeasible. 相似文献
