Research on Energy-saving Algorithm of Wireless Sensor Network
Abstract
In wireless sensor networks, the nodes around the base station have higher energy consumption due to the forwarding task of all the detected data. In order to balance the energy consumption of the nodes around the base station, this paper proposed a reasonable and effective mechanism of node rotation dormancy. In this way, a large number of redundant nodes in the network are in a dormant state, so as to reduce the load of important nodes around the base station. In this paper, we analyzed the problem of the redundant nodes in the sensor network, and proposed a new method to distinguish the redundant nodes based on local Delaunay triangulation and multi node election dormancy mechanism. The experimental results showed that this method could effectively distinguish the redundant nodes in the network; at the same time, through the multi round election mechanism, we make part of redundant nodes dormant and reduce the network energy consumption on the condition of guaranteeing the original coverage.
