Research of Node Sleep-scheduling Algorithm in Wireless Sensor Network

摘要

It is an important issue that how to use the node sleep-scheduling at the same time ensure the quality of covering in the design of Wireless Sensor Networks.This paper adopts the random deployment and random sleep mode based on considering border effects,and gives covering model of energy saving which do not rely on the information of any position.The model describes the relationship on the node perception radius,monitoring region radius,node quantities,sleeping probability and coverage quality.It can offer effective foundation to Wireless Sensor Networks nodes' sleeping parameters.Simulation experiments have verified the accuracy of the model.
