While wireless LAN technology has made its way into the market with easy-to-install wireless routers and 802.11a/b/g wireless cards, the flat-architecture ad hoc wireless networks with no infrastructures are still under research and development in many industrial laboratories and research groups. We have developed a communication theoretic framework [1] and conducted experiments using an ad hoc wireless network emulator [2] developed in our Intel Wireless Lab to verify our analytical results. However, with the current hardware available in the market, the performance is limited to the 802.11 MAC protocol and analysis of large networks with many participating mobile devices is not plausible with the current test bed setup due to hardware limitation. The focus of this work is on developing a routing algorithm which takes as input parameters from the Physical and MAC layer. In order to test the routing protocol we developed and achieve scalability, we use OPNET to model the routing protocol and simulate both small and large scale networks. [1] O. K. Tonguz and G.
