农田无线传感器网络节能协作节点分布研究

In order to save the battery energy of farmland multi-hop wireless sensor network(WSN) and prolong its service life, comparing the battery energy consumption of direct link and two-hop relay link in WSN by using the collaborative communication's energy consumption model, studying the distance of source node and destination node, the area and the optimal position of relay node when the battery energy consumption of two-hop relay link is lower than direct link's and analysis the influence of some factors. This paper can provide reference for the deployment of farmland multi-hop WSN in order to save the battery energy.
