Abstract Information of sensor percept are send to interested target node through sensor network. The multicast technology in traditional networks are usually more energy consumption, worse real-time. It is not fitted in sensor network. For nodes is unknown of network topology, multicast routing issue is converted to the optimal multicast path issue firstly, and it is solved through the heuristic algorithm. The multicast routing tree is optimized through cutting merger strategy with greedy, the optimal path is got in the entire network. Finally, combined with the node area concentration and wireless multicast characteristics, a routing algorithm, named DCast, is proposed. Finally, simulation results demonstrate the advantages of energy consumption and delay compared with other classic multicast routing algorithm such as uCast, SenCast.
