A self-configuration management model for clustering-based MANETs

Self-configuration management of mobile ad-hoc networks (MANETs) depends upon the hierarchical architecture and topology change of the network. By analyzing role shift and behavior changes of nodes in the clustering-based MANETs, a self-configuration management model is proposed in this paper. In view of unpredictability of the node behavior, a cluster unit provides the auto-configuration mechanisms with the node entry-exit and the clusterhead replacement control loops to adjust to changes of the network. The node entry-exit control loop resolves configuration as a result of nodes' movements. Configuration processes such as parameter reconfiguration, service publication will be executed once again in the clusterhead replacement control loop when the original clusterhead loses effectiveness. Based on this, two scenarios are depicted to give an analysis in model commonality aspects. Results of simulation prove a better performance of our model. In this paper, we describe the interoperate actions between cluster members and the cluster head to enable each cluster system to self-maintain in its life cycle.
