摘　　要：本文基于无线Ad Hoc同络的特性,提出了适用于无线Ad Hoc同络的路由协议CEQRP(Cost-Efficient QoS Routing Protocol),该协议不仅能为应用层提供QoS保证,而且能充分利用网络中剩余能量高的节点来中转分组,从而达到有效利用节点的电能、提高网络"寿命"的目的。在仿真研究中,我们考虑了在不同虚电路数以及不同QoS要求的情况下,各节点采用CEQRP和QRP(QoS Routing Protocol,选择路由时除不考虑节点剩余电能,其它方面与CEQRP相同)时的网络性能。结果表明,在中等业务强度下,CEQRP与QRP郝具有较好的网络性能,而且CEQRP在有效利用节点电能方面性能优越。In this paper, a novel CEQRP (Cost-Efficient QoS Routing Protocol) for mobile Ad Hoc network is proposed. CEQRP can provide QoS guarantee and is aimed at extending the battery's lifetime at each node by selecting the nodes with a long battery's remaining lifetime to forward packets. In the performance experiments, VC traffic flows with different QoS types and different VC connections are considered. Simulation results show that both CEQRP and QRP (the same protocol as CEQRP except that it does not consider the lifetime at each node when selecting routing) have good network performance. Furthermore, CEQRP shows distinct performance advantages in using a node's electric energy efficiently.
