Abstract
Mobile ad hoc networks (MANETs) allow mobile nodes to communicate among themselves via wireless multiple hops without the help of the wired infrastructure. In the MANET, it is required not only a route setup mechanism that makes nodes not within each other's transmission range communicate but also mechanism in order for a node to auto-configure a unique address. In this paper, we propose an address auto-configuration mechanism when MANET is connected to the Internet via several Internet Gateways and all gateways advertise the same network prefix. By using the proposed mechanism, once a node configures an Internet topologically correct and globally unique IP address, then the node can utilize the configured address even though the node moves within the MANET. Through the simulations, we analyze the performance of our proposed mechanism and, from the simulation results, we show that out proposed mechanism outperforms the existing mechanism.
