中文摘要：
信道分配是多射频多信道（multiradio multi channel,MR-MC）AdHoc网络的关键问题之一。为提高MR-MCAdHoc网络吞吐量和端到端时延,在分析当前多射频多信道网络的信道分配算法的基础上,提出了衡量信道性能的度量参数CP（channel performance）并以发送和接收双方测量得到的CP值为依据设计了信道分配算法PCAA（performance-based channel allocation algorithm）,以解决网络信道公平接入和分配不合理的情况,从而达到提高网络性能的目的。仿真结果表明：算法在保证网络连通性的前提下,合理分配了信道,显著增加了网络的平均吞吐量,并降低了端到端平均时延。
英文摘要：
Channel allocation is one of the key problems in Multi Radio Multi Channel.To improve the throughput and end to end delay of the MR-MC Ad Hoc networks,we present a new metrics ＂CP＂ for measuring channel performance and Performance-based Channel Allocation Algorithm（PCAA） based on analyzing current channel allocation algorithm in Multi Radio Multi Channel,which aims at improving network performance by solving fairness on channel access and reasonableness on channel allocation.The simulation results show that the proposed algorithm can rationally assign channel,dramatically increase the network throughput and reduce the end to end average delay on the premise of network connectivity.
