WIRELESS SENSOR NETWORKS COVERAGE-ENERGY ALGORITHMS BASED ON PARTICLE SWARM OPTIMIZATION

In wireless sensor networks (WSN) coverage is an important aspect in measuring the quality ofservice of the network. Network with mobile WSN is able to improve its coverage by moving thesensor nodes so that a better arrangement is achieved. However sensors movement consumesenergy. In this paper three algorithms are presented to optimize coverage of mobile WSN while atthe same time taking energy usage into consideration. The algorithms proposed are based onparticle swarm optimization (PSO). PSO is chosen due to its good performance record. Based onthe tests conducted, the algorithms successfully achieve their objective.
