Region segmentation model for wireless sensor networks considering optimal energy conservation constraints

Abstract

In order to improve the life cycle of wireless sensor networks as well as reducing the energy cost, the structural optimization and energy conservation for region segmentation are designed. A region segmentation model for wireless sensor networks based on optimal energy conservation constraints is proposed. The initial network topology for node distribution of wireless sensor networks is constructed. The equivalent network-wide energy balance topology is used for optimal calculation of the coverage area of the sensor network and the shortest path optimization method is used for energy conservation design for sensor network nodes. According to the energy attribute of sensor nodes, the coverage area of wireless sensor networks is segmented optimally to improve the coverage of wireless sensor networks and reduce the energy cost of a single node in the network, to realize the optimal networking of wireless sensor networks. The simulation results show that for the region segmentation model of wireless sensor networks constructed by this method, the quality reliability of transmitting data by network nodes is higher, the regional coverage is stronger and the energy cost is lower, compared with previous works, which effectively prolong the life cycle of wireless sensor networks.
