Abstract
CPS,a heterogeneous distributed system,is composed of a variety of heterogeneous network com-munication.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 (QoS),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 hierar-chical 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.关键词
