Area double cluster head APTEEN routing protocol-based particle swarm optimization for wireless sensor networks

摘要: APTEEN is a typical routing protocol for wireless sensor networks, but when clustering, cluster heads are randomly selected, which makes it easy to select nodes with low residual energy as heads, thus forming network holes. At the same time, in multi hop transmission, head near sink node overloaded due forwarding large amount of data. Aiming at these problems, this paper introduces PSO algorithm and proposes ADCH-EPE-APTEEN protocol. In order make particle swarm optimization more suitable protocol, first DCA-PSO based on algorithm. uses classification adaptive change inertia weight different states particles process. dynamic learning factor used improve influence experience other convergence speed accuracy Secondly, networked, selected by DCA-PSO, nodes, location distribution around fully taken into consideration. Thirdly, considering distance between node, front area set up located upper half assistant through The simulation results show that can significantly search precision compared Compared reduce consumption rate extend lifetime 173%.
