Abstract :
A novel routing scheme called GeO-LANMAR routing has been proposed in this paper. This scheme combines the local link-state routing protocol until k-hop and a long-distance greedy forwarding. Geo-LANMAR supports group motion and gives high scalability for large network. It uses the concept of local group area (LGA) to define region where to forward data packets through geo-forwarding scheme. It makes usage of a virtual topology between LGAs and an optimized Hazy sighted link state (HSLS) link-state routing protocols. It combines the benefit of LANMAR protocol in terms of group motion support with the scalability of terminodes routing. A hybrid forwarding scheme (proactive and geo-routing) and a coarse topology knowledge through the HSLS protocol running between LGAs is applied. A performance evaluation of Geo-LANMAR vs. other routing protocols such as AODV, LANMAR and GPSR has been lead out
