一种改进的适用于实时业务的DSR协议

A Modified DSR Protocol for Real-time Traffic

AdHoc网络拓扑结构的动态变化使得实时业务的服务质量(QoS)在其中很难得到保障。针对此问题,提出了一种改进的DSR协议——IDSR(Improved Dynamic Source Routing)。IDSR通过为实时业务和非实时业务采用不同的发送功率来传输数据,从而满足实时业务的QoS。仿真结果表明,IDSR降低了端到端的平均延时以及减少了路由平均跳数。

Because network topology may be changed at any time as result of mobility of nodes and the failure of available mutes, Quality-of-Service （QoS） of real-time application may have difficulty in satisfying their services in Ad Hoc network. In this paper, we propose a routing scheme for real-time services called Improved Dynamic Source Routing （IDSR） protocol. The IDSR selects the shortest path by using different power levels for real-time traffic and non-real-time traffic. Simulation results show that the IDSR achieves lower average end-to-end delay and mean hops from source to destination than DSR protocol can provide.
