Abstract:
Ad Hoc networks are multi-hop wireless networks consisting of mobile hosts. 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.
