They do not have any pre-existing network infrastructure and are characterized by constantly changing topology, limited battery power and bandwidth. Typical applications of such networks are battlefield networks, medical relief during natural calamities or disasters, conference room networking, and intra-vehicular communications. Routing packets in an ad-hoc network is a challenge because of the mobile nature of the nodes and the constantly changing topology. In ad hoc networks, each mobile node functions as a router, forwarding packets, establishing routes and helping each other in maintaining the network. A novel scalable routing protocol SLURP (Scalable Location Updated-based Routing Protocol) addresses these issues of ad hoc networks routing. The protocol is based on a location management strategy, which keeps the routing overhead to a minimum. In this thesis we compare the protocol against an existing set of multi-hop ad hoc network routing protocols that cover a range of design choices: DSDV, TORA, DSR, and AODV. We implemented SLURP in the network simulator ns-2, with the necessary wireless extensions. Experiments were run to simulate changes in network topology, number of active sources, link connectivity, and speed of motion. The difference in performance and scalability are illustrated.
