In recent communication technologies and services the Mobile ad hoc network place an increasingly vital role, that dynamically establish the connection whenever required for the communication network resulting in a quickly changing in topology of the network and increase communication overheads. This dynamic topology, leads to significant routing overhead, scalability problems and battery power consumptions in MANETs. Consider this problem, in this paper a clustering approach have been proposed for ad hoc networks. In Clustering approach, the cluster head election is call upon for the constructing the path, reduce the communication over heads and scalability. For the path construction cluster-AODV routing protocol is applied and also the design goals of clustering algorithms are presented.

“…Overlapping clusters might have nodes that are common among them which are called gateways [14] . MANET requires efficient routing algorithm in order to reduce the amount of signaling introduced due to maintaining valid routes [5] [10] , and therefore enhance the overall performance of the MANET system. As the clusterhead is the central node of routing for packets destined outside the cluster in the distinct clustering configuration, the clusterhead computing machine pays a penalty of unfair resource utilization such as battery [1] , CPU, and memory.…”

Mobile Ad Hoc Network (MANET) consists of dynamic topology as nodes in the network are mobile, and connected via wireless links. The nodes are grouped in clusters for the purpose of routing. Nodes within the cluster communicate directly. However, nodes communicate outside the cluster through a centralized node that is called a clusterhead. An elected clusterhead is assigned for communication with all other clusters. The centralized clusterhead can become a bottleneck and possibly cause a lower throughput for the clustering system. We propose a mechanism in which communication outside the cluster is distributed through separate clusterheads. We prove that the overall averaged throughput for the clustering system increases considerably, about doubles for our distributed number of clusterheads. We also show that the increase in overall averaged throughput is reduced by the increase in the overall averaged error rate ratio resulting from the added clusterheads. Additionally, the routing reliability to outside the cluster is increased since routes to different clusters use distinct clusterheads.
