title = "Enhancing the spectrum utilization in cellular mobile networks by using cognitive radio technology",
abstract = "The rapidly increasing number of cellular mobile users and services increases the cellular mobile spectrum scarcity problem of the fixed cellular mobile spectrum (CMS). Cognitive radio (CR) is a new promising technology which aims to overcome this spectrum scarcity problem by enhancing the utilization of the cellular mobile communication spectrum. The channel allocation and re-allocation is a vital part of cellular mobile networks (CMNs) to enhance the utilization of the CMS. In this paper we propose a new channel allocation and reallocation scheme to enhance the spectrum utilization of CMNs by integrating cognitive radio technology and a new channel allocation scheme called Channel Allocation with Cognitive Radio (CACR). MATLAB simulations have been used to evaluate the performance of CACR with particular emphasis on probability of call blocking and handover failure. The simulation results show that the proposed channel allocation scheme enhances the cellular mobile spectrum utilization.",
