摘要： 描述了一种在Ad Hoc网络中基于熵度量的MAODV协议（EMAODV），提出了衡量路径稳定性的新尺度——熵，利用熵的度量来选择长寿的、稳定的路径，减少了重构路由的次数，在Ad Hoc网络的网络拓扑频繁变化的环境中较好地提供QoS保证。仿真实验结果表明，EMAODV协议快速有效，具有较高的可靠性。EMAODV协议为动态Ad Hoc网络的建立和评价稳定的路径提供了一种新的有效
途径。

Abstract: MAODV routing protocol provides fast and efficient route establishment between mobile nodes that need to communicate with each other. MAODV has minimal control overhead and route acquisition latency. In addition to unicast routing, AODV supports multicast and broadcast as well. This paper presents an entropy-based metric to support long-life MAODV(EMAODV). The key idea of EMAODV protocol is to construct the new metric-entropy and select the long-life path with the help of entropy metric to reduce the number of route reconstruction so as to provide QoS guarantee in the Ad Hoc network whose topology changes continuously. The simulation shows that the EMAODV protocol is efficient and effective. The EMAODV approach and parameters provide an accurate and efficient method of estimating and evaluating the route stability in dynamic mobile Ad Hoc networks.

Key words: Multicast routing, Routing protocol, Entropy, Multicast Ad Hoc on-demand distance vector(MAODV)
