摘要
大多数为自组织网络设计的路由协议都假定IEEE 802.11b用于最低层通信。在IEEE 802.11 ad hoc模式中，DCF是基本的介质访问协议。本文以基于802.11b MAC的移动自组网语音呼叫为研究对象，提出了一种新的基于扩展AODV协议的自组网稳定路由度量。仿真结果表明，与标准的AODV协议相比，新协议可以提高ad hoc网络上VoIP的性能。
An extended AODV protocol for VoIP application in mobile ad hoc network
Most of the routing protocols designed for ad hoc networks assume that IEEE 802.11b is used for lowest-layer communications. In IEEE 802.11 ad hoc mode, the DCF is the basic medium access protocol. In this paper we consider voice calls over mobile ad hoc network based on 802.11b MAC. A new routing metric for searching a stable routing in ad hoc network based on an extended AODV protocol is proposed. The simulation results presented in this work show that the new protocol can improve performance of VoIP over ad hoc network as compared to standard AODV protocol.
