Abstract
In this paper, we propose an address autoconfiguration mechanism and a route establishment mechanism appropriate for the modified MANET architecture which overcomes the multi-link subnet problem. For the delivery of Router Advertisement (RA) messages without causing the duplicate packet reception problem in the multi-hop wireless network environment, the Scope-Extended RA (Scope-Extended Router Advertisement) message is defined. Also, by defining the MANET Prefix option, a MANET node is allowed to send packets destined to a host not in the MANET directly to the gateway. This can prevent the performance degradation caused by broadcasting control messages of the reactive routing protocol for route establishment. The performance of the proposed mechanism is analyzed through NS-2 based simulations and, according to the simulation results, it is shown that the proposed mechanism performs well in terms of the control message overhead.
