Secrecy transmission capacity in noisy wireless ad hoc networks

Secrecy Transmission Capacity in Noisy Wireless Ad Hoc Networks

This paper considers the transmission of confidential messages over noisy wireless ad hoc networks, where both background noise and interference from concurrent transmitters affect the received signals. For the random networks where the legitimate nodes and the eavesdroppers are distributed as Poisson point processes, we study the secrecy transmission capacity (STC), as well as the connection o...

Ad hoc wireless networks with noisy links

Models of ad-hoc wireless networks are often based on the geometric disc abstraction: transmission is assumed to be isotropic, and reliable communication channels are assumed to exist (apart from interference) between nodes closer than a given distance. In reality communication channels are unreliable and communication range is generally not rotationally symmetric. In this paper we examine how ...

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...
