A Scalable Routing Scheme for Self-Organized Terminode Network

The focus of this paper is routing in a wide area mobile ad hoc network referred to as a Terminode Network. Our routing scheme is a combination of two protocols: Terminode Local Routing (TLR) and Terminode Remote Routing (TRR). TRR is used for remote destinations. It utilizes the location of a destination obtained by the source using location management or location tracking. TLR acts when the packet gets close to the destination. The use of TRR results in a scalable solution that reduces dependence on the intermediate systems, while TLR reduces problems due to the destination location inaccuracy. This paper describes TLR and TRR and the interaction between them. Terminode routing is implemented and evaluated using GloMoSim simulator. For the purpose of more realistic routing evaluation we designed a new mobility model, the restricted random waypoint model, which represents more realistic mobility pattern in a large scale mobile ad hoc environment.
