摘　　要：文章针对多射频多信道ad hoc网络的特点,提出了一种信道分配方法和路由策略。新的信道分配方法在保持网络连通性的基础上能够简化信道分配,减少信道分配的冲突;新的路由策略综合考虑了带宽、信道差异、射频切换时延、信道间干扰等链路参数以及最小跳数等因素,更能准确地反映被选路由的链路质量。Aiming at characteristics of multi-radio multi-channel ad hoc networks, a new method of channel assignment and a new route strategy are proposed in the paper. The presented method of channel assignment can maintain network connectivity, simplify channel assignment and reduce collb sion of channel assignment. The new route strategy takes account of link bandwidth, channel diversity, radio switching delay, channel interference and the shortest hop as routing metrics and can capture real link quality of the route selected.
