A Cellular-Based Routing Algorithm for Ad-Hoc Wireless Networks

In this paper we present a routing algorithm when an ad-hoc network is in the coverage of a cellular network. To perform routing in ad-hoc network, the proposed algorithm exploits topology information of ad-hoc network that obtained from base station in cellular network. Two routing scenarios regarding to ad-hoc nodes capability are considered. Cellular network is just used to accomplish routing for ad-hoc network. After performing the routing through the centralized management system in cellular network, requester ad-hoc node forwards data via its Wi-Fi interface according to the discovered route in the ad-hoc mode. Our results show that the proposed routing protocol outperforms pure AODV and DSR protocols in terms of end-to-end delay, routing overhead, and packet delivery ratio.
