摘要 基于MAC层的定向技术,提出了一种适合于Ad hoc无线网络的协议——APRP协议,协议考虑了MAC层和网络层信息的共享和交互,改进了动态源路由协议DSR的路由发现和路由维护机制.采用NS2工具对协议性能进行了仿真研究,结果表明APRP协议不仅可以利用定向技术能量利用率的优势,而且还能较好地保持节点移动情况下的吞吐量,降低端到端数据包延时和路由开销. Incorporating directional technology of MAC layer into Ad hoc wireless network, a network routing protocol suitable for Ad hoc network and named APRP was proposed, which enhances information sharing and interacting between MAC and network layers, and improves the route discovery and maintenance mechanism of protocols DSR （ Dynamic Source Routing）. Simulation results based on the NS2 demonstrated that APRP protocol benefits with better energy utilization from the adopted directional technology, notably retains the throughputs in case of node mobility, and reduces end-to-end packets delay and routing overheads.
