摘　　要：在资源受限的无线传感器网络中,组播由于能够有效的利用网络带宽并降低服务器的负担因而受到广泛的关注。提出了一种基于区域的组播路由算法,该算法中采用了分簇的结构,并能够根据传感器网络的能量和带宽都有限的特点和组播成员的分布动态的调整组播树的形状,从而能够在低开销的情况下为无线传感器网络提供良好的性能。Muhicasting has gained much attention in recent years because it can efficiently utilize network bandwidth and reduce the load at application servers in the resource-constrained wireless sensor networks.In the paper,we put forword a muhicast routing algorithm based on region divided method,this algorithm adopt the clustering hierarchy structure,and it can adjust the multicast tree according to the characteristic of the limit of energy and link bandwidth in wireless sensor networks and the locations of muhicast group membership,thus it can provide good performance to group members with low cost in wireless sensor networks.
