摘要
提出了一种新的QoS路由保障协议,该协议是在按需距离矢量路由(AODV)协议的基础上引入QoS保障机制扩展而成。它将带宽作为QoS路由保障的先决条件,延时和分组丢失率作为优化的目标,更好地保障了无线自组网的服务质量。仿真结果表明,该协议能较大地改善网络的性能,在QoS保障上优于AODV协议。
The new QoS routing protocol to ensure the QoS in mobile Ad Hoc network (MANET) was put forward. The new protocol was an expansion which is based on AODV protocol. With bandwidth as the prerequisite for QoS guarantee and the delay and packet lost rate as the optimized targets, it provided better assurance for QoS in MANET. The simulation results present that the new protocol improves the performance of MANET and make more advantage than AODV in QoS guarantee.
