Improving the Efficiency of Call Admission Control in Wireless Cellular Communication Networks by Frequency Sharing Techniques
Journal Title: INTERNATIONAL JOURNAL OF COMPUTER TRENDS & TECHNOLOGY - Year 2014, Vol 9, Issue 3
Abstract
In this paper, a two-tier cellular communication wireless network is characterized by overlapping the service area for managing the new calls users having different mobility speed. The overlapping property of the two-tier system provides the advantages that share the traffic load to improve the efficiency of new calls subscriber with reservation of channels (guard channels) in cell to handle the ongoing old calls (handoff calls). Microcells are used to provide the services to slow-speed, high-intensity traffic area users and macrocells are overlaid over more than one microcells cater mainly too lower density, high-speed users. The two-tier of microcells and macrocells provide the secondary resource which provide the service to new calls as well as handoff calls with guard channels by overflow the slow speed users in macrocell and sharing the frequency in vertical as well as in horizontal directions in the upper layer. In this paper, we tried to optimize use of resources by using advantage of overlapping coverage of two-tier wireless cellular networks and frequency sharing techniques like VDFS and HDFS. The call lose probability of new calls are developed through numerical analysis. The VDFS and HDFS schemes are proposed and compared with the existing schemes of CAC. The result shows the new proposed schemes are more efficient.
