Nodes in contention-based (beaconless) georouting forward packets towards a known destination position without the knowledge of the neighborhood. The only existing methods that guarantee delivery in unit disk graphs (UDG) require runtime planarization of the communication graph with either unbounded message overhead per hop while preserving the Gabriel graph property of the subgraph, or a constant...
We study the problem of power-efficient routing for multi-hop wireless ad hoc sensor networks. The guiding insight of our work is that unlike an ad hoc wireless network, a wireless ad hoc sensor network does not require full connectivity among the nodes. As long as the sensing region is well covered by connected nodes, the network can perform its task. We consider two kinds of geometric random graphs...
