| Abstract: | In order to prolong the lifetime,reduce the energy consumption and balance the network load effectively,a corresponding algorithm of task assignment in wireless sensor network based on particle swarm optimization is proposed.This algorithm describes a cost function according to the execution time and energy consumption.PSO is used to optimize task allocation.Meanwhile,a mutation operator that can effectively improve the algorithm's ability on global search and maintain population diversity is also introduce... |
