Issues and challenges in clustering techniques for wireless mesh networks

Abstract

The implementation of wireless mesh networks (WMNs) for large scale use is not very easy because the topologies in these networks are multihop and highly dynamic while the bandwidth issue is also a great limitation . Despite the huge advantages that this technology portends its implementat ion has been seriously affected by myriad of challenges, thus clustering schemes are proposed by various authors to confront these challenges. In this paper, some existing clustering technique schemes are perused with the mindset to reveal the huge benefits that such scheme offers when implemented while we also in- tend to point out some of its weaknesses for the re search community to find a way of fine-tuning it for its betterment. Clustering techniques were classified in this paper according to their implementation criteria such as heuristic, weighted, emergent and hierarchical while the advantages and weaknesses are technically highlighted.
