Abstract: Based on the analysis of existing Ad Hoc network clustering algorithms, this paper proposes a novel on-demand weighted clustering algorithm named EMCDA. By considering the mean connectivity degree and energy status of mobile nodes and adopting the on-demand strategy, it improves the stability of the network architecture and lowers the computing and communication costs. Analysis and simulation result prove the validity of the algorithm.

Key words: Ad Hoc network, clustering algorithm, mean connectivity degree, energy status, weight
