Capacity of Wireless Ad Hoc Networks

Wireless ad hoc networks have become an important area of research in wireless communications systems. Unlike some existing networking technologies such as Internet Protocol (IP) networks or cellular systems, wireless ad hoc networks have the advantage that deployment of networks does not require preexisting infrastructures. Ad hoc networks have neither fixed topology nor centralized servers; i...

Core Capacity of Wireless Ad Hoc Networks*

In this paper, we model energy-limited wireless ad hoc networks as non-transferable-utility cooperative network flow games. We define the %ore capacity region” of a wireless ad hoc network to be the set of Pareto-optimal utility vectors that cannot be blocked by any proper subset of the node set. We show that the core capacity region is non-empty under the linear utility model. Under the many-t...

Ultra Wide Band Ad-Hoc Sensor Networks: A Multi-Layer Analysis. (Réseaux de capteurs ad-hoc Ultra Wide Band : une analyse multi couche)

and Thesis Overview Abstract The Ultra Wide Band (UWB) technology represents a promising approach allowing the development of new types of wireless Local Area Networks (LANs) and Wireless Sensor Networks (WSNs). For twenty years, UWB has been an active field of research and it could be the physical layer for future multiple access wireless networks with very high bit rates, as well as low bit r...

Capacity regions for wireless ad hoc networks

We define and study capacity regions for wireless ad hoc networks with an arbitrary number of nodes and topology. These regions describe the set of achievable rate combinations between all source-destination pairs in the network under various transmission strategies, such as variable-rate transmission, single hop or multihop routing, power control and successive interference cancellation.
