摘要
Abstract
Network congestion produced by many to one communication is a crusial problem in WSN. In allusion to the limited lifetime for WSN nodes, the relative information entropy of the node is introduced, and a node-level congestion avoidance mechanism is proposed. The relative information entropy of nodes is calculated to distribute data window for upstream nodes, and then the upstream nodes send the data packets according to the size of the received data window. The simulation analyses show that the proposed algorithm can effectively avoid the loss of network data packets, reduce the delay of network transmission and also has the excellent energy effectiveness.关键词
