中文摘要：
基于IEEE 802.11 DCF协议和竞争转发的思想,提出了一种适于移动Ad Hoc网络的路由协议,即基于竞争的跨层路由（CCR）协议。协议采用位置信息辅助的BRTS/CTS/DATA/ACK四次握手机制实现对数据包的竞争转发,通过区分优先级的方法解决空洞通信问题。最后,在OPNET仿真平台下对CCR协议进行了性能评估。仿真结果表明,与DSR协议和LAR1协议相比,CCR协议具有较高的数据包投递率、较低的端到端时延和较小的控制开销。
英文摘要：
Based on contention forwarding and IEEE 802.11 DCF protocol,a contention-based cross-layer routing （CCR） protocol for mobile ad hoc network was proposed.It implements the contention forwarding of DATA packets by utilizing BRTS/CTS/DATA/ACK four-time handshake mechanism,which is aided by location information,and solves the void communication problem by means of differentiating priorities.The performance of the CCR protocol was evaluated on OPNET simulation platform.Simulation results show that CCR outperforms DSR and LAR1 protocols in terms of packet delivery ratio,end-to-end delay and control overhead.
