Bandwidth and Energy-Efficient Route Discovery for Noisy Mobile Ad-Hoc Networks
… such as Ad-hoc On-demand Distance Vector (AODV) commonly employ pure flooding based broadcasting to discover new routes. In pure flooding, a route request (RREQ) packet is broadcast by the source node and each receiving node rebroadcasts it. This continues until the RREQ packet arrives at …
