| 摘 要： | 针对多媒体数据的特点论述了在Ad hoc网络环境中各性能参数的要求,利用NS2仿真软件模拟了在Ad hoc网络环境中利用AODV,DSR及DSDV路由协议进行多媒体数据传输,并将网络吞吐量、延时抖动等4种多媒体数据敏感参数进行了比较.实验表明,由于多媒体数据类型的不同,AODV,DSR及DSDV协议的性能也各有差异,通过比较发现,DSDV的表路由机制不能满足Adhoc网络的多媒体业务要求,DSR可用于QoS要求不高的视频传输,AODV可用于传输视频及音频,但对延时要求较高的数据则不能满足.

| Abstract: | This article describes the characters of multimedia data and the requests for translating the data in the Ad hoc networks.The network simulation software NS2 are used to simulate the transmission of multimedia data in the Ad hoc network environment by AODV,DSR and DSDV protocols.The crucial parameters for multimedia data's transmission,such as the throughout rate and delay jitter,are analysed.The experiment shows that using different protocols to transmit different types of multimedia data,the capacities of AODV,DSR an d DSDV are diverse.DSDV protocol can not meet the requirement for multimedia data operation in Ad hoc environment because of the routing table mechanism,DSR could transfer the video data which is not too strict in the quality,AODV could transfer the video and audio data without high quality in delay. |
