摘要

针对异构网络环境中的接入网选择问题，使用李雅普诺夫优化理论对网络进行建模，并提出了使不同接入网络的剩余服务时间差异最小的选择算法。该算法在保证网络稳定的基础上，在长时间尺度内降低了网络的阻塞率。仿真表明，该算法可以提高网络的利用率，降低用户被拒绝的概率。

Abstract

Due to the problem of how to select the most suitable access network for users at any time anywhere in heterogeneous wireless networks(HWN)

a distributed algorithm to minimize the difference of residual service time between different access networks was proposed.The algorithm use the Lyapunov optimization to model the network and guarantee the stability of the network.Simulation results show that the proposed algorithm can decrease the rejection ratio and achieve a shorter queue length in access networks.
