Abstract: Ad hoc networks regional coverage control algorithm has some problems including low covering efficiency, high energy consumption and poor transmission reliability. A cellular-genetic regional coverage cooperative control algorithm based on triangle subdivision (CRCCTS) is proposed on the basis of analyzing the network models of ad hoc networks. The CRCCTS algorithm takes the vertex structure of outer polygon of node coverage area as the datum, and divides the network coverage area into several subdomains through triangulation. Based on the dyeing scheme, the nodes at the subdomain vertices are defined as frequency nodes, and the cluster range is determined according to the different signal spectra after region division. Finally, the cellular genetic idea is used to solve the power control mode of self-organizing cooperative network nodes in the consideration of communication energy consumption and idle energy consumption. Simulated results show that, when the number of nodes is large (100-500 nodes),the coverage efficiency of CRCCTS algorithm can reach up to 3%,the energy consumption is reduced by at least 2 J, and the average end-to-end reliability is increased by at least 9.5% compared to balanced rate area coverage algorithm, discriminant construction algorithm for minimum node strong barrier, coverage configuration protocol algorithm, and multi-hop Ad Hoc wireless network energy-saving technology algorithm.
