Integrated ad-hoc and cellular networking in indoor or faded environments
Jean‐Michel Dricot, Philippe De Doncker · 2009
The latest developments and experimentation in wireless ad-hoc networks show that their use might provide a reliable coverage extension to cellular networks. The integration between 3rd Generation/4th Generation (3G/4G) and ad-hoc networks may offer a great number of benefits in term of deployment cost, accessibility, peer-to-peer (P2P) traffic redirection, etc. While the Open Systems Interconnection (OSI) reference model advocates for a clear separation of routing, transmission and physical layers, in this paper we show that an effective routing algorithm requires knowledge and constructive interaction between these layers. More precisely, we propose the use of a new routing algorithm, derived from the Ad-Hoc On-Demand Distance Vector (AODV) algorithm, based on the physical aspects of the wireless medium and optimized for indoor transmissions. Our results emphasize the possibility of a reliable cellular coverage extension in indoor environments, on the basis of a beneficial cross-layer interaction between routing, power control, transmission, and propagation.
