A Protocol for Efficient Bi-directional Connectivity between Ad Hoc Networks and Internet

Abstract

The integration of infrastructure networks and ad hoc mobile networks can be used to eliminate dead zones in wireless LANs and cellular networks, and can also be used to extend the coverage of wireless networks. Earlier approaches for the integrated networks either provided only unidirectional global connectivity for ad hoc hosts or caused high overhead and packet delay for bi-directional connections. In this paper, a protocol for integrating mobile IP and enhanced DSDV (EDSDV) is proposed to provide bi-directional Internet connectivity for ad hoc hosts. A detailed performance comparison is conducted between the proposed approach with a leading integration approach based on different network sizes, mobility of ad hoc hosts and other network parameters. The experimental results show that the proposed approach has smaller overhead for bi-directional connectivity and shorter average packet delay compared to the leading integration approach.
