Towards an adaptive resource management scheme for mobile cellular network

Due to the tremendous increase in both the size of the wireless mobile community and demand of high bandwidth by resource hungry applications, efficient radio resource management is one of the most important issues in wireless communication nowadays. A good resource management scheme should support as many mobile users as possible while maintaining the necessary quality of service. Flexibility to adapt the dynamic nature of the communication infrastructure depends on some factors other than available bandwidth, such as, density of users, percentage of reservation for handoff and new calls etc. In this paper, we present and analyze a flexible and dynamic resource management scheme, namely Dynamic Resource Allocation with Flexible Reservation (DRAFR), which is specially tailored to support the emerging traffic in a wireless and mobile network. Extensive analysis and graphical results are shown to demonstrate the efficacy of our scheme with regard to traditional Quality of Service (QoS) parameters when compared to other resource allocation schemes.
