Inside MANET, mobile devices can move independently devoid of pre established infrastructure. In this type of network there is no fixed topology for the network. To increase the coverage range and to obtain the global type of services these MANETs can be joined to other type of networks. For combination of heterogeneous type of networks, intermediate one which is a gateway is used to form a hybrid network. In MANET, security issues also play a vital part during data communication since sender to sink. So in our work, we are combining MANET with Internet to form a hybrid network and for the interconnection between heterogeneous networks gateways are adopted and for identification and selection of those gateways, adaptive gateway discovery approach is employed and to enhance security feature encryption and decryption with authentication is taken into consideration.
