Abstract

When the mobile ad hoc network (MANET) is connected to the Internet, it is important for the mobile nodes to detect available Internet gateway (IGW) providing access to the Internet. We propose a new structure--virtual MANET ( V_MANET) for MANET to connect with Internet. In the structure, the IGWs are seen as a fixed node in MANET and act as a proxy server in the local area network (LAN). At the same time, we develop the IGWs discovery, Deleting IGW, Exchanging IGW _INFO between two neighbor nodes and IGW selection algorithm applied in the V_MANET. The result of evaluation shows that our architecture and these algorithms can improve network performance and is more efficient.
