移动自组网中基于路径稳定性的QoS路由协议

A QoS Routing Protocol Based on Path Stability in Mobile Ad Hoc Network

随着多媒体应用日益普及 ,在移动自组网中提供QoS已经逐渐成为自组网研究的热点问题 然而现有的自组网QoS路由协议主要集中研究如何找到满足QoS条件的可行路径而没有考虑可行路径的稳定性 针对移动自组网的特点 ,提出了基于路径稳定性的QoS路由协议PSQRP ,该协议基于路径稳定性PSF来选择路由 ,减少了链路断开的概率 同时协议采用了主次预约技术来预约网络资源 ,进一步提高了协议的请求成功率 模拟结果表明 ,在动态的网络环境下 。

With the prevalence of multimedia application, it has become a research focus to provide QoS in ad hoc mobile network However, current QoS routing protocols concentrate on finding a feasible path that satisfies QoS conditions and overlook path stability According to the features of ad hoc network, a QoS routing protocol PSQRP is proposed which is based on path stability The protocol selects a route in term of path stability and reduces the probability of link breakage It increases the request success ratio by using the technology of primary and secondary reservation The simulation results show that the protocol gains good performance in dynamic network environment
