Optimal sensor deployment scheme for heterogeneous mobile wireless sensor networks using differential evolution algorithm
摘要
Abstract
To solve the problem of the sensor deployment in the monitored area characterized by a geographical irregularity of the sensed events, a dynamic sensor deployment strategy based on differential evolution algorithm (DE) for heterogeneous mobile wireless sensor networks (WSNs) was proposed. To the objectives of guaranteeing efficient coverage of network, the position vector of each population in the algorithm was updated according to the historical local and global optimal solutions which could enhance convergence speed. Simulation results demonstrate that the proposed approach is suitable for solving deployment problems of heterogeneous WSNs, with better performances in the convergence and searching than virtual force algorithm. Therefore, this method can implement dynamic sensor deployment efficiently and rapidly.关键词
