摘要
Abstract
The Threshold-Stable Election Protocol(TSEP)does not consider the residual energy of the node and the dis-tance from the node to the base station, which causes some low-energy nodes to die prematurely when the cluster head is elected. The cluster head also sends the data directly to the base station, which also causes the node to run out of energy and die prematurely. An improved energy-efficient routing algorithm for heterogeneous wireless sensor networks is pro-posed for the above problems. The new algorithm improves the threshold formula by considering the distance from the node to the base station, the number of neighbor nodes, the residual energy of the node and the average distance between the node and the neighbor node. The data forwarding path of the double-layer cluster head model is improved by the improved ant colony optimization algorithm. The simulation results show that the proposed algorithm extends the life cycle of the network and improves the stability of the entire network.关键词
