Integrated connectivity framework for Internet and ad hoc networks

Abstract

The integration of the Internet and ad hoc mobile hosts can be used to eliminate dead zones in wireless networks, and can also be used to extend the coverage of wireless networks. The integration enriches the application range of ad hoc networks. Earlier approaches for the integrated networks either provided only unidirectional global connectivity for ad hoc hosts or caused high overhead and delay for providing full bi-directional connections. In this paper, an enhanced DSDV (EDSDV) protocol is proposed for ad hoc networks. The EDSDV protocol is integrated with Mobile IP to provide full bi-directional Internet connectivity for ad hoc network hosts. This approach has smaller overhead for full bi-directional connectivity and also shorter average packet delay compared to other integration approaches.
