  The implementation of MANET for commercial purposes is not an easy task.
Unlike other wireless technologies such as cellular networks, MANET face more
difficult problems concerning management functions, routing and scalability .
As a solution to these complications, clustering schemes are proposed for MANET
in order to organize the network topology in a hierarchical manner. Many
clustering techniques have been developed. Clustering is a method which
aggregates nodes into groups. These groups are contained by the network and
they are known as clusters. By Increasing network capacity and reducing the
routing overhead through clustering brings more efficiency and effectiveness to
scalability in relation to node numbers and the necessity for high mobility.
The manager node in clustering has responsibility for many functions such as
cluster maintenance, routing table updates, and the discovery of new routes
within the network. The other node named as gateway node communicate to the
other cluster. In this paper we remove the cluster head (CH) and given a new
approach in which cluster head and gateway will be same and that node is known
as cluster head gateway (CHG), in which all the responsibilities of cluster
head and gateway will be perform by the Cluster head gateway(CHG) itself. By
applying this approach we reduce of overheads and improve the over all
performance of the network while throughput will be same in both condition with
the help of Exata simulation.
