Summary:Wireless Sensor Network (WSN) can be considered as scale-free weighted network which reflects the existing form and dynamic characteristic, such as application of mobile control and so on. Multicast communication is an effective way to save energy, bandwidth, cost and other resources in WSN, so we propose an Extended Ad hoc On-Demand Distance Vector (EAODV) routing method based on distributed minimum transmission (DMT) multicast routing for WSN in this paper. According to the causes of uncertain information of WSN such as random load, data fusion or other impact factors, the DMT-based EAODV routing method chooses the forwarding routes which can connect more multicast receivers to solve routing optimization problem. The method proposes a dynamic strategy to change the multicast tree structure based on the characteristic of node mobility of WSN. Experimental results demonstrate that the method effectively improves the efficiency of multicast routing. The obvious advantage and novelty of the proposed method is its good performance in package loss rate, throughput, energy consumption and delay.
