【摘要】 由于CPS是一个异构的分布式系统,由多种异构的网络通信构成。多种网络融合的研究是CPS网络进一步发展的重要任务。在建筑环境下,CPS为满足用户需求,提高通信服务质量(Qo S),需要选择一个最佳接入网络,否则会产生降低服务质量的不良后果。最佳接入网络的选择受几个因素的影响,面对传统算法考虑参数单一问题。本文提出一种利用层次分析,计算权重再进行加权平均计算决策的异构无线网络选择算法。通过仿真结果证明,利用改进的异构网络融合算法可以提高网络吞吐量,提升服务质量。更多还原

【Abstract】 CPS, a heterogeneous distributed system, is composed of a variety of heterogeneous network communication. The study of network integration is an important task of the CPS network further development. In building environment, in order to meet users’ requirements and improve the quality of service(Qo S), we need to choose a best access networks in the CPS. Otherwise, it will lead to adverse consequences of service quality. The choice of optimal access networks is influenced by several factors. In the face of traditional algorithm parameters of a single subject, this paper puts forward a heterogeneous wireless network selection algorithm through hierarchical analysis, which calculates weights and then makes weighted average calculation decision. The simulation results show that the improved fusion algorithm of heterogeneous network can improve the network throughput, as well as the service quality.更多还原
