Abstract :
We present the caching and multipath (CHAMP) routing protocol, a new protocol for mobile ad hoc networks that uses data caching and shortest multiple path routing to achieve both robustness against mobility and energy-efficiency. Simulation results show that a 5-packet FIFO data cache combined with 2 routes exhibits significantly better performance compared to DSR (dynamic source routing) and AODV (ad-hoc on demand distance vector) routing. At very high loads, CHAMP outperforms DSR and AODV, delivering 50% and 30% more packets, respectively, while consuming 1/3 and 1/2 less energy (per packet delivered), respectively.
