主　　题：Ad Hoc Multi-channel Channel handoff Network throughputs Routing 

摘      要：How to improve the performance of the wireless Ad Hoc network by utilizing the spectrum resources efficiently has become a hot research topic in recent years. In this paper we propose a reactive routing algorithm that supports multiple channels to improve the performance of the Ad Hoc network based on the minimizing of the channel handoff. Our approach allocates the communication channel during the route discovery, and notifies the allocated channel information to the corresponding node in the route reply packets. Each node in the route tries its best to choose the same channel with the upstream node without interference. The simulation results show that our algorithm performs better than the K-hop distinct protocols in both average delays and network throughputs
