Performance Analysis of the MANET One-Hop Clustering Algorithm in Group Mobility Models

Many mobile ad hoc network applications depend upon the hierarchical structure. Clustering is the most popular method to impose a hierarchical structure in the ad hoc networks. This paper aims at the deficiency of the clustering algorithm performance analysis in group communication applications. Based on analyzing the characteristics of the mobility model and typical clustering algorithms, five major one-hop clustering algorithms are compared and evaluated using the group mobility model RPGM in the paper. Drawbacks of the current clustering algorithms under the group mobility model are pointed out and the implications on the clustering algorithms in group communication applications are discussed in the end.
