Data Rate and Fragmentation Aware Ad hoc Routing

Abstract

We propose to use two link adaptation strategies together in order to find energy-efficient routing paths in an ad-hoc network: exploiting different modulation techniques supported by the physical layer and the fragmentation size of the packets. Our proposed mechanism finds the best (modulation technique, fragmentation size) pair for a given link and uses this information for finding the minimum energy routing paths. We provide a modified version of the well known AODV protocol and show that our proposed mechanism performs better than the two mechanisms deployed individually and much better than the original protocol.
