| Abstract: | Multicasting 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 multicast 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 multicast group membership,thus it can provide good performance to group members with low cost in wireless sensor networks. |

| Keywords: | multicast routing region divided method clustering hierarchy multicast tree |
