Mobility of nodes is considered as the potential solution for improving Ad Hoc network performance, such as maintaining a specified network topology, improving the power efficiency, and enhancing signal-to-noise ratio at the receivers, etc. However, node movement consumes certain amount of energy, which is limited at nodes, and should be counted when optimizing the system performance. In this paper,...
In order to improve coverage of randomly deployed wireless sensor networks, a distributed deployment algorithm based on coverage addition factor (CAF) is proposed. In this algorithm, each node acquires the distribution of overlapped coverage arcs on the sensing circle based on its neighbors?? positions and moves in the direction the coverage addition factor is the greatest. With the algorithm iterated,...
