Abstract

Channel allocation is one of the fundamental issues in wireless communications due to the fact that it determines how the available bandwidth will be managed. The limited channel availability and the increasing demands for advanced services such as real time video give to channel allocation strategies a special role. Plethora of channel allocation strategies have been proposed in the literature for supporting voice services as well as multimedia services. In large scale networks, where the traffic conditions can not be predicted, intelligent techniques have been applied such as genetic algorithms. This paper, presents a critical overview on the recent advances in the most important channel allocation strategies found in the literature with regards to voice and multimedia services. Moreover, a discussion for the existing channel allocation strategies and the applicability of intelligent techniques, based on the computational intelligence framework, is also presented.
