Distributed energy balance routing algorithm for wireless sensor network based on multi-attribute decision-making

Abstract

The clustering routing protocol proposed in this paper is based on the Low Energy Adaptive Clustering Hierarchy (LEACH) protocol. Stable Election Protocol (SEP) is a clustering routing protocol proposed for secondary heterogeneous networks. Unlike LEACH, it is not a round-robin algorithm based on the number of nodes, but based on energy balance. This article first promotes SEP and adapts it to multi-level heterogeneous networks. On this basis, the Stable Election Protocol Energy Consider (SEP-EC) algorithm based on node residual energy is proposed, and its feasibility is proved theoretically. The research results show that for the Ad Hoc network with high load, high mobility and energy limitation, the load energy balance multi-path routing protocol proposed in this paper can not only effectively use multiple paths with better quality, but also can perceive path stability in real time. It terminates the call of unstable path early, and effectively reduces the packet loss rate, delay and route discovery frequency of Ad Hoc network. The average end-to-end delay of the SEP-EC protocol proposed in this paper is 0.52 s, and the average remaining surviving nodes is 83.5%.
