提出了一种适用于Adhoc网络中的多媒体会议系统模型,该模型结合了移动IPv6技术和SIP(session initiation protocol)技术,并对传统的AODV(Ad hoc on-demand distance vector)路由算法路由进行了修改,使其可以很好地匹配系统模型.将传统的AODV算法和修改后的算法应用到系统模型中,对会话中移动节点在不同Ad hoc网络间的切换进行了研究.仿真结果显示,修改后的AODV路由算法性能可以将切换时的时延抖动和分组丢失率改善50%左右.

A system model for multimedia conference which could be deployed in Ad hoc networks is proposed.Mobile IPv6 and SIP are implemented.Classic AODV routing algorithm is modified in order to adapt this system model.Both classic AODV routing algorithm and modified AODV routing algorithm are implemented in the system model,and handover is investigated in the middle of a mid-multimedia conference between two ad hoc networks. Simulation results show the modified AODV routing algorithm could efficiently improve the performance on jitter and packet loss rate,up to 50%.
