摘要
传感器网络中节点极为有限的资源使得组播的实现非常困难。本文基于最短路径算法，并结合定向扩散模型的优点提出了一种在传感器网络实现组播路由算法的可行算法。算法能够较好的适应由于节点失效或者移动等情况造成的拓扑变化，并能减少大量的能量耗费，具有较好的性能。
Severe limitation of nodes＇ resources in sensor network makes it very difficult to carry out the muhicast. Based on the shortest path algorithm and combining the advantages of directional diffusing model, the essay gives a suitable algorithm to carry out the multicast routing in SN. The algorithm can deal with the topological change caused by the void nodes or the moving of them, and can reduce the large expenditure of energy. The algorithm has a better performance.
