Mobile adhoc network(MANET) is penetrating our society as a future technology in our day to day life.Today mobile ad-hoc network has lot of application like in disaster management, tactical network, sensor networks etc.But its implementation for commercial purposes is not an easy as compare to other exiting wireless technologies such as cellular networks.It has many challenges or issues that offer many problems concerning mobility managements, shared radio medium, routing protocol and scalability.To overcome such issues many approaches has been described.Clustering schemes are one of them in order to manage/organize the larger network in hierarchical manner.So many clustering techniques have been developed.Clustering is a scheme which divide large network into small manageable networks or group.These groups are called clusters.Clustering increases network capacity and reduces delay and the routing overheads and make the network manageable and efficient in the presence of high mobility and large number of nodes.In hierarchical network every cluster has a group leader node which has many responsibility such as e to manage that cluster,, routing table updates, and the discovery of new routes within the network.The other node named as gateway node is responsible for inter cluster communication.But the frequent change of cluster leader and gateway node leads loss of routing information stored, inefficient performance of routing protocols, more delays, more overheads and makes the network unstable.In the proposed approach in place of cluster leader and gate way node , a new node named as Cluster leader gateway(CLG) node id selected and all of the taskof cluster leader and gateway node is performed by the this single CLG node itself .The propose CLG approach is simulated and compare with existing approach the help of Exata Cyber++ simulator and performs better for the parameter end to end delay,jitter,number of packets drop and link utilization.
