Asymptotic uniform data-rate guarantees in large wireless networks

In this paper, we study asymptotic uniform data-rate guarantees in large wireless networks from an information-theoretic viewpoint. We consider the following question: what is the maximum achievable data rate that such a network can support for communication from an arbitrary radio node to its destination under transmission power and network-topology constraints, as the network size goes to infinity? In other words, we study the data-rate guarantee for an arbitrarily chosen source-destination pair assuming all other nodes act as relays. We consider two types of network deployments: 1)a regular deployment with unreliable nodes; and 2)a random deployment. We provide upper and lower bounds on the asymptotic achievable data rate for both linear and planar topologies under the two deployment models.
