Wireless sensor network node deployment and power supply method

Abstract

The invention relates to a wireless sensor network node deployment and power supply method. The method comprises the steps of establishing a network node topological structure communicated with and covered by a network, determining the positions of energy consumption hotspots in a current network node topological structure by utilizing a preset data routing path selection algorithm according to the network node topological structure, carrying out deployment of renewable energy source nodes according to the positions of the energy consumption hotspots, and carrying out deployment of battery nodes on other network nodes in the current network node topological structure, dynamically adjusting power supply strategies of the battery nodes according to the power supply states of the renewable energy source nodes. Through the wireless sensor network node deployment and power supply method, under the restriction of limited number of the renewable energy source nodes, according to the positions of the energy consumption hotspots of the network, the number and the positions of the renewable energy source nodes can be determined, the combined deployment of different energy source nodes can be completed, the work tasks and the states of different nodes can be determined according to the conditions of collection and transformation of renewable energy sources, and the continuous stable work of the network and the maximized utilization of the renewable energy sources can be achieved.
