Performance Evaluation of Speed Sensitive Handover in Two-Tier Wireless Networks

Abstract

In today’s scenario, due to urban development where subscribers are increasing day-by-day with high density and distributed in non-uniform manner with high and slow speed in moving nature. The two-tier cellular networks’ infrastructure may help in sharing the traffic load of versatile speed of users and accommodate more subscribers by taking the advantage overlapping property of two tier wireless networks. It may helps in sharing the channels and handover the calls in horizontal as well as vertical direction. Frequency management and call admission control techniques may help in resource optimization in result of adjust more subscribers. In this paper, fuzzy logic adaptive channel management strategy using two-tier wireless networks is presented. Macro-microcells taking the advantage of overlapping the property in results of optimization of resource utilization show seamless handoff to adjust the more subscribers and improve the overall performance of the wireless cellular networks.
