Due to insufficient frequency band and tremendous growth of mobile users and number of services demanded by the users inspires the researches to find out the new aspects of wireless communication. As the number of nodes increases complexity of MANET increases in various issues. For this reason various approaches has been produced to reduce the complexity such as cluster head technique and dominating set based gateway technique introduced. In our paper we remove the limitation from the above mentioned approaches 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 CHG and we introduces the prediction table concepts in such a way that if CHG node moves or left the network then which node will act as the CHG, because if without giving the responsibilities of CHG to any node the rest of the node of that cluster has strong chances to loss the network. By applying this approach we will reduce the overhead for deciding the cluster and gateway for an adhoc network and by maintaining the prediction table we can decide which node will work as CHG in future.
