The Research Progress and Future Perspective of Clustering Algorithm for Wireless Multi-Hop Network
Ying Gao, Liangfang Ni, Jianjian Chen · 2014
The extremely poor performance owns to interference, attenuation, multi-path, path loss and shadowing. It makes it impossible to guarantee the quality and the reliability of the single hop communication between two nodes with long distance in mobile Ad-hoc network. The cooperative diversity could be achieved to counterbalance the above affects, once the multi-hop virtual mul- ti-antenna system was implemented with the aid of clustering the nodes. In terms of the static and dynamic clustering, this paper analyzed the characteristics of clustering schemes, according to the exploration of the mutual information accumulation with the aid of distributed space-time coding for dynamic clustering, in the light of the investigation of clustering schemes based on signal to noise ratio and Viterbi algorithm. On the basis of current achievement on theory and practice of clustering techniques and their essential relation, the proposals for future research and develop- ment were presented.
