摘　　要：在Ad Hoc网络中,节点变化较大,而ZRP协议预置半径的做法,不能有效利用网络资源。针对此问题,提出了基于带宽和延时的BD-ZRP协议。在定义节点半径时,引入带宽和时延参数,实时改变半径大小,以适应动态网络变化,从而提高路由性能。通过NS2仿真表明,改进后的BD-ZRP协议在包投递率和时延方面比传统ZRP协议具有更好的性能。The nodes change greatly in Ad Hoc network. That the ZRP protocol presets radius, can＇t effectively use network re- sources. Aiming at the problem, BD-ZRP protocol based on bandwidth and delay is proposed in the paper. After defining the radius of nodes, the bandwidth and delay are introduced. The radius of the network is changed real-timly to adapt to the change of the net- work, and to improve the performance of the routing. The NS2 simulation results show that the improved BD-ZRP protocol has a good performance than the traditional ZRP protocol in terms of packet delivery ratio and delay.
