DESIGN AND PERFORMANCE ANALYSIS OF AN EFFICIENT DISTRIBUTED FAULT TOLERANT CHANNEL ALLOCATION ALGORITHM FOR CELLULAR NETWORKS

Abstract

ABSTRACT Efficient allocation of communication channels is critical for the performance of wireless mobile computing systems. The centralised channel allocation algorithms proposed in earlier literature are neither robust nor scalable. Here in this dissertation, we present a distributed dynamic fault tolerant channel allocation algorithm. The algorithm does not need a central network switch. The mobile service station of a cell makes all the decision about the channel allocation in the cell. The mobile service station of a cell makes all the decision about the channel allocation in that cell based information available locally. The MSS only needs to exchange information with its neighbours within the co-channel interference range. Unlike the fixed channel allocation algorithm (FCA) the proposed algorithm can adapt to changing load distribution in the network. It is more robust than existing DCA algorithms as it does not depend on a central network switch whose failure could bring down ...
