In wireless sensor networks, the connectivity-based localization protocols are widely studied due to low cost and no requirement for special hardware. Many connectivity-based algorithms rely on distance estimation between nodes according to their hop count, which often yields large errors in anisotropic sensor network. In this paper, we propose a virtual potential field algorithm, in which the estimated...
In recent years, wireless sensor and actor networks (WSANs) have been extensively deployed to monitor physical environment and facilitate decision making based on data collected. Emerging applications such as road surveillance highlight some interesting research issues in WSANs, including coordination problems in sensor-actor or actor-actor communications. In this paper, the issue of choosing a set...
Since automated fault localization can improve the efficiency of both the testing and debugging process, it is an important technique for the development of reliable software. This paper proposes a novel fault localization approach based on multi-level similarity of execution traces, which is suitable for object-oriented software. It selects useful test cases at class level and computes code suspiciousness...
Data-centric storage is an effective and important technique in sensor networks, however, most data-centric storage schemes may not be energy efficient and load balanced due to non-uniform event and query distributions. This paper proposes EEBASS, it utilizes an approximation algorithm to solve the optimal storage placement problem according to the variance of event and query distributions, aiming...
Large-scale software systems usually consist of a huge number of modules, and have a series of releases along with these modules. This can be seen as software evolution. In recent years, researchers have put forward several models of software evolution by employing the theory of complex networks. In this paper, we put forward a refined model of software evolution based on the BA model: module-based...
