Clustering is an efficient method for increasing scalability in mobile ad hoc networks. In this method. several nodes called clusterheads are responsible for serving the nodes in their cluster. Choosing the optimal number of clusterheads can improve the quality-of-service metrics such as delay in clustered networks. https://hryino3ejqdr.timeblog.net/70683004/comparison-of-parameters-and-fitness-of-different-time-dependent-and-time-independent-independent-variables-in-survival-analysis
