In order to effectively alleviate the problem that,the node closer to the Sink node,the earlier it will die in underground chain-type wireless sensor networks,this paper puts forward an improved algorithm based on the SPIN algorithm for WSN in underground,the algorithm combined with the narrow straight roadway model and multiple coverage model,using the gradient method of partitioning and judging the gradient information of received ADV to decision data information receiver,balance the energy consumption of entire network,and extend the network lifetime. The improved energy loss model algorithm can prolong the network lifetime efficiently,simulation results show that the improved algorithm can extend the network lifetime at least 5% than that of NCWSNFGM.
