Channel Import Efficiency of the DonorList Algorithm

Abstract

Rapid advances of the handheld devices and the emergence of the demanding wireless applications require the cellular networks to support the demanding user needs more effectively. The cellular networks are expected to provide these services under a limited bandwidth. Efficient management of the wireless channels by effective channel allocation algorithms is crucial for the performance of any cellular system. To provide a better channel usage performance, dynamic channel allocation schemes have been proposed. Among these schemes, distributed dynamic channel allocation approaches usually have better performance results. The two important issues that must be carefully addressed in such algorithms are the efficient co-channel interference avoidance and messaging overhead reduction. One of these distributed channel allocation algorithms is the DonorList algorithm, which can effectively manage these two issues. In this paper the channel import efficiency of the DonorList algorithm is evaluated. The performance evaluation results obtained after extensive simulation studies, which were conducted under different traffic load conditions, show that the proposed algorithm provides improvement over the performance of other algorithms recently proposed in the literature.
