摘要

选择最优接入网络是确保网络资源有效分配和提高网络整体性能的有效手段。提出一种基于跨层感知的接入选择方法CN_CLA，构建跨层感知框架模型以获取影响接入网性能的主要评估参数，采用模糊理论对可接入网络的性能进行综合评测，应用量子遗传算法对评判权值进行优化，最终实现接入网络的智能选择。实验结果表明，CN_CLA能够在无用户干涉情况下合理地选择接入网络，并在吞吐量、时延、会话完成率、分组丢失率等方面优于链路容量法、H_RSSI_S及AS_FTM接入选择算法。

Abstract

Accessing to the optimal network was an effective way of ensuring the efficiency of network resources utilization and improving network performance.An access point selection mechanism based on cross-layer awareness for cognitive networks(CN_CLA)was proposed.Firstly

a cross-layer cognitive framework was constructed for obtaining the primary evaluation parameters that influence the performance of network access.Secondly

the fuzzy theory was applied for evaluating the access network performance comprehensively

and the weights in each layer were optimized using the quantum genetic algorithm

and then the access point was selected intelligently.Simulation results show that the proposed method chooses reasonable access networks without intervention of users.Furthermore

it is superior to the traditional methods

including the link capacity scheme

H_RSSI_S and AS_FTM

in terms of throughput

delay

session completion rate

packet loss and other performance indicators.
