| 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... |
