| 摘 要： | 针对基于树的组播路由协议中组播树鲁棒性不好,扩展能力差的特点,又结合无线传感器网络自身能量、计算、存储能力有限的特点,提出了基于虚拟Steiner树的组播随机路由协议VMRRP(Virtual-steiner-tree based Multicast Random Routing Protocol)。该协议的随机路由思想,使得组播树中源节点到各个组成员节点的路径是动态变化的,与GMP(Geographic Multicast Routing)协议相比,增加了组播树的鲁棒性,也均衡了网络能量,增加了网络生命周期,并通过NS-2仿真试验得到了验证。

| Abstract: | Tree-based multicast routing protocol usually has a less robust and less expansible multicast-tree,for this reason,we propose a Virtual-steiner-tree-based Multicast Random Routing Protocol(VMRRP),concerning a limited energy,computing and storage power environment in wireless sensor networks.The thought of random routing proposed in this protocol makes the route from source to each destination a dynamic one.When comparing to GMP,it equilibrates the energy consumption and make the network's life span much longer,which is verified by simulation with NS-2. |
