WSN Multicast Routing Protocol for Region-specific

For the uneven distribution and high-energy consumption problems of Wireless Sensor Network(WSN),this paper proposes a region-specific multicast routing protocol for WSN.The use of group head rotation mechanism,node with more energy reserves and the optimal location forward packets to other nodes,node with less energy reserves is responsible for data acquisition.Using multi-mode forwarding group to establish a stable route,improve network robustness and reduce data latency.Simulation results show that the agreement will achieve a balance of energy consumption and extend the network lifetime.
