一种改进的基于移动预测的可扩展多播路由协议

移动Ad Hoc网络是由一组带有无线收发装置的移动节点组成的一个支持多跳的临时性的网络自治系统，随着网络应用规模的增长，在移动Ad Hoc网络中支持多播路由成为网络领域中一类重要的研究课题。在MAODV的基础上，提出了一种采用基于优先权指数的竞争广播算法以及基于移动预测的主动路由维护机制的改进多播路由协议，仿真结果表明改进后的协议减少了开销、降低了时延，有效地增加了协议的可扩展性。

Advanced scalable multicast routing protocol with mobility prediction for Ad Hoc networks

An Ad Hoc network is a multi-hop wireless network that is composed of mobile hosts communicating with each other through wireless links.As the number of participants increase,the scalability of the multicast routing protocol becomes an important issue.In this paper,based on M-AODV,an improvement protocol with the priority-based competitive broadcasting algorith-m and the mobility prediction-based routing maintenance is presented.Results obtained through simulations demonstrate that the improved protocol reduces end to end delay,and enhances packet delivery ratio and scala- bility of the proposed techniques.
