Research On Heterogeneous Wireless Network Admission Control Algorithm

Wireless network communication technology along the two main lines of development and has made great achievements.Different network has different advantages and disadvantages,heterogeneous network can make full use of the advantages of each other,to avoid the impact of the shortcomings.However,heterogeneous network is complex,so there are a lot of problems,such as resource management of heterogeneous networks,access control of heterogeneous networks,and so on.In this paper we focus on the handover problem of wireless heterogeneous network.This paper is mainly through the improvement of heterogeneous wireless network simulator,collect simulation results,analyze the impact of movement parameters and network parameters on the network performance,so as to realize the research of heterogeneous network handover problem.Simulation results show that the mobile user has great influence on the network performance.When the user is moving at an even speed,the move speed higher,the user drop rate higher,the block rate will be higher,the user satisfaction decrease;when the user is variable motion,the greater the acceleration,the user drop rate and block rate become higher,the user satisfaction decrease.In this paper,the influence of resource reserves on resource utilization is studied.The experiment results show that the resource utilization rate of wlan network is invariant and stable.But,the reservement resource amount of cell network higher,the resource utilization rate higher.The simlator improvement of this paper lay a foundation for the research of the reaserch of optimal resource reservation algorithm.
