摘要
为了提高无线多跳网络中组播树的可靠性和提高组播效率,提出了一种基于声誉机制的组播协议.该协议在构建组播树时考虑了节点的声誉值,从而将自私性节点排除在组播树之外,使得构建的组播路径比较可靠.仿真实验表明该协议可以用较低的代价有效地提高组播效率.
To improve the reliability of the multicast tree and the efficiency of multicast,a multicast protocol based on reputation mechanism was proposed.The protocol took into account reputation value of the nodes in constructing the multicast tree,thus excluding the selfish nodes from it,making the multicast path comparably reliable.Simulation results show that proposed protocol can significantly improving the efficiency of multicast at a lower cost.
