To connect the wired and wireless networks particularly the Mobile ad hoc Network is very interesting in real world situations due to its popularity and usefulness. Different mechanisms have been proposed to integrate MANETs and the Internet. These strategies differ in gateway discovery mechanism, cell switching criteria, ad hoc routing protocol. 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 Ad hoc network and by maintaining the prediction table we can decide which node will work as CHG in future to make our communication unaffected.
