The mapping of cellular architecture into mobile ad hoc network (MANET) leads to the design of Linked Cluster Architecture (LCA), where every cluster has a head node associated with zero or more member nodes. In order to achieve a faster cluster setup, we consider mobility of nodes as the deciding parameter for selecting the heads and their associated members. A node having the lowest mobility among its neighbors becomes the cluster head. Selection of low mobile nodes as the cluster heads ensures better cluster stability. A new energy consumption model has been considered for the cluster heads that takes into account the network traffic, density of cluster members and the transmission power utilized to communicate the member nodes.
