MPLB:a Load Balance Scheme of Joint Resource Scheduling in Heterogeneous Wireless Network

摘要：

　　A user terminal with multi-mode wireless interface is always located its position in the covered area of heterogeneous wireless network(HWN),there are too many algorithms about vertical handover(VHO)of multiple attributes decision making(MADM)network selections about HWN.According the analysis of current applications of wireless service,regular service has been classified into four kinds,including voice,video,small data and big data,and the proportions of wireless video and big data service may acquire an unavailable bandwidth for each individual wireless station,which will lead to a heavy load and a lower satisfaction rate.A multiple properties load balance(MPLB)scheme is proposed to solve this joint resource scheduling(JRS)problem properly,MPLB scheme first gave an enhanced architecture including the JSR sub-layer,then model of MPLB is established from the candidate wireless network,five aggregated network performance properties have been defined mathematically,the candidate of best grey relational coefficients(GRC)of grey relational analysis(GRA)algorithm is optimally selected as the final executable scheme,after the description of a general flowchart of MPLB scheme.The simulation results proved the MPLB scheme has a more stable load balance effects than those of VHO,so did most users of MPLB gain higher satisfaction rate,slightly different with the four kinds of service.It can be concluded theoretically that the MPLB scheduling scheme could achieve both the load balance on the service providers side and the increased quality of experience of satisfaction rate on the wireless user side,which would bring out some new thoughts in the future user centric network.
