ABSTRACT
The primary goal of future cellular mobilecommunication networks is to provide efficient andcost effective services to mobile users under allenvironments. The major issues that affects the qualityof service and performance in wirelesscommunications systems is scarcity of resources.Hence, efficient resource allocation is prime concernin order to improve the performance of cellularnetworks. Two-Tier cellular system is considered toincrease the channel utilization by sharing channelsbetween two tiers. In this paper a Hybrid ChannelAllocation (HCA) strategy for channel allocation and queuing technique is applied to hierarchical cellular network in order to enhance the performance of the system. The hierarchical cellular system helps better utilization of radio spectrum and application ofqueuing technique further increases efficiency of the system by reducing call blocking and dropping and by increasing number of users in the system.
