Optimization of APTEEN Routing Protocol in Wireless Sensor Networks Based on Particle Swarm Optimization

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 cluster heads, thus forming network holes. To solve this problem, this paper uses particle swarm optimization (PSO) to optimize APTEEN routing protocol. When APTEEN routing protocol networking, considering the residual energy of the node, the location of the node and the energy distribution around the node, the particle swarm optimization is used to select the cluster head. The simulation results show that the optimized APTEEN routing protocol significantly prolongs the network lifetime and reduces the network energy consumption rate.
