Optimal Coverage Mechanism Based on PSO Algorithm in Wireless Sensor Networks
Junnian Wang · Computer and Modernization · 2009
An optimal model for coverage in wireless sensor network is established.Then a Stochastic Multi-objective PSO(SMOPSO) based on binary coding is proposed,to compute the max-coverage area of working sensors and the min-number of working sensors.And the network redundancy are reduced to extend network lifetime.The simulated results show that the optimal coverage scheme proposed in this paper can satisfy the requirement of low nodes utilization rate and high coverage rate.
