A data transmission protocol for WSN based on multi-strategy improved whale optimisation algorithm

This paper is a study of routing protocols for wireless sensor network (WSN) based on the whale optimisation algorithm (WOA), which has problems such as slow convergence, low convergence accuracy and the tendency to fall into local optimality. Firstly, a multi-strategy WOA named CNGS-WOA is proposed, which includes chaotic mapping, nonlinear processing of convergence factor and golden sine partition. The simulation results show that the CNGS-WOA has obvious advantages in terms of search accuracy and stability. Secondly, a data transmission protocol named CNGS-WOA-RP is proposed based on the improved WOA. By comparing four aspects of network clustering effect, network life cycle, network residual energy and network energy consumption balance, it's shown that the data transmission protocol CNGS-WOA-RP can effectively reduce and balance network energy consumption, and has greater advantages in extending network lifetime.
