Ad hoc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,在分析标准DSR协议的基础上,总结DSR在实时性方面的不足并加以改进,提出一种的具备良好实时性质的优化了的动态源路由协议.我们称之为RT-DSR(Real-Timed DSR).仿真结果表明,改进的协议和原协议相比,降低了端到端的时延和丢包率,提高了传输效率.Ad hoc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,在分析标准DSR协议的基础上,总结DSR在实时性方面的不足并加以改进,提出一种的具备良好实时性质的优化了的动态源路由协议.我们称之为RT-DSR(Real-Timed DSR).仿真结果表明,改进的协议和原协议相比,降低了端到端的时延和丢包率,提高了传输效率.
The dynamic change of the topology of Ad hoc network makes it difficult to guarantee the quality of service (QoS) of real-time services.On the basis of analyzing the standard DSR protocol, this paper summarizes the shortcomings of DSR in real-time and improves it, An optimized dynamic source routing protocol with good real-time properties is called RT-DSR (Real-Timed DSR) .The simulation results show that the improved protocol reduces the end-to-end delay compared with the original protocol And packet loss rate, improve the transmission efficiency.Ad hoc network topology of the dynamic changes in the real-time business so that the quality of service (QoS) in which it is difficult to be guaranteed.In response to this problem, based on the analysis of the standard DSR protocol, summarizes the DSR in We propose a dynamic real-time routing protocol with good real-time properties, which we call Real-Timed DSR. The simulation results show that the improved protocol and the original protocol Compared to reduce end-to-end delay and packet loss rate and improve the transmission efficiency.
