Mobility analysis and Framework proposal on Clustering and Validation Mechanisms for Ad Hoc Network

S.Thirumurugan , Dr. E. George Dharma Prakash Raj


The mobility of the nodes affects the compactness of the clusters. This ends up with the decline in the performance of the clustered ad hoc networks. Thus, while the clusters move to worst state in their performance, re-clustering should be suggested. But this process will be considered as overhead of the network if the re-clustering time hasn’t been decided properly. The validation mechanisms should be applied to decide the re-clustering time of the ad hoc network. This research work shows the analysis of the clusters periodically where the nodes are dynamic in nature. This analysis has been done for 10 nodes as a sample set. The measures are done for time periods T1, T2, T3 and T4. The results are tabulated to make a decision on the re-clustering. This work also incorporates a framework for the clustering and validation mechanism.
