The integration of Internet and ad hoc mobile network exhibit differences in their network architecture. Thus, the interconnection is achieved by using Internet gateways, which acts as bridges between MANET and Internet. When a node in ad hoc network wants to access Internet, it has to first find route to a gateway. Therefore an efficient gateway discovery approach or mechanism is required. In this paper, the MANET routing protocol ad hoc on demand vector (AODV) is extended to support hybrid network. The three approaches for discovering gateways such as reactive, proactive and hybrid are compared and studied in different scenarios. We show that proactive and reactive performs better in different simulation environment.
