Recently, Internet connectivity in mobile ad hoc network (MANET) has been studied extensively in order to support ubiquitous Internet services to MANET users and provide interworking with other networks such as wireless local area network (WLAN) and cellular networks to extend the coverage of these networks. Although there have been a lot of works on connecting MANET with Internet, few works have been performed on the detailed performance analysis of the effect of routing path discovery for Internet connection from MANET with reactive routing protocol such as ad hoc on demand distance vector (AODV) protocol from the aspect of routing discovery delay and control overhead. In this paper, we propose a hierarchical mobile AODV6 network architecture, which combines the concept of hierarchical Mobile IPv6 and AODV ad hoc routing protocol. In the proposed architecture, Internet gateway performs the role of mobility anchor point (MAP) of hierarchical Mobile IP (HMIP), and a novel routing path discovery and data delivery scheme is proposed by managing address information of connected nodes in Internet gateway. Then, the performance of the proposed scheme is analyzed in terms of routing path discovery overhead and control packet overhead for Internet connection from AODV6 node. The result shows that the proposed scheme has lower control packet overhead and routing path discovery delay compared with conventional AODV6 scheme. © 2007 IEEE.
