A Node Sleeping Method for Industrial Wireless Sensor Networks Based on Cellular Automata

Abstract

The invention discloses a dormancy method for industrial wireless sensor network nodes based on cellular automata. The method of the present invention specifically introduces the cellular automata theory into the wireless sensor network facing the industrial background, regards a large number of sensor nodes in the wireless sensor network as cells in the cellular automata, and each sensor node only needs to By mastering the information of itself and its neighbor nodes, it can decide its working or dormant state. The Thiessen polygon partition method is used to determine the irregular cell space and the node neighbor set, thus ensuring that each cell space contains only one sensing node; at the same time, environmental factors such as industrial noise and the remaining energy level of the node are considered in the state transition. In the design of the rules, the problem between the reliability and energy consumption of industrial wireless sensor networks can be effectively solved, so as to improve the utilization rate of sensor nodes and prolong the life of wireless sensor networks.
