The increasing demand for enabling MANET nodes to connect to IP based fixed infrastructure wired networks and use their services and applications requires the cooperation of MANET routing protocols and IP mobility protocol. The integration of MANETs to the fixed infrastructure IP access networks is useful in many scenarios. MANET users can access the wired network and the Internet and access a range of services and applications. In this paper, we have proposed a framework which provides Connectivity to MANET node to the wired network using Mobile IP enabled gateway nodes. We implement Mobile IP with DSDV protocol to provide Connectivity between hybrid MANETs. The proposed framework is simulated in the ns2 simulator, and the performance of the proposed framework is evaluated on the basis of packet delivery ratio, average end to end delay and throughput under different scenarios.
