This paper presents an efficient algorithm for channel assignment problem in cellular radio networks. The task is to find channel assignment with minimum frequency bandwidth necessary to satisfy given demands from different nodes in a Wi-MAX network. This paper deals with a Dynamic Channel Allocation (DCA) technique based on an energy function whose minimization gives the optimal allocation. The performance of the proposed DCA technique is here derived by computer simulations. Comparisons with a classical fixed allocation technique and a different DCA technique are shown to highlight the better performance of the proposed DCA technique.
