In this paper we consider secret communication between two special nodes ("source" and "destination") in a wireless network with authenticated relays: the message communicated to the destination is to be kept information-theoretically (unconditionally) sec ...

This thesis studies communication and agreement protocols in wireless ad hoc networks from both theoretical and practical perspectives. The last decade has given rise to the rapid growth of wireless telecommunications such as cellular mobile phone networks ...
In many wired and wireless networks, nodes process input traffic to satisfy a network constraint (e.g., a capacity constraint) and to increase the utility of data in the output flows given these constraints. In this paper we focus on the special case in wh ...
The paper addresses the media-specific rate allocation problem in multipath networks. The streaming rate on each path is determined such that the end- to-end media distortion is minimized, when the receiving client aggregates packets received via multiple ...
The privacy of users of mobile devices has been at stake, with emerging systems based on the mobile ad hoc networking technology raising additional concerns. The establishment of a connection between two nodes could readily reveal information to an eavesdr ...
We characterize the fairness of decentralized medium access control protocols based on CSMA/CA, such as IEEE 802.11, in large multi-hop wireless networks. In particular, we show that the widely observed unfairness of the protocol in small network topologie ...

Solving consensus in wireless ad hoc networks has started to be addressed in several papers. Most of these papers adopt system models developed for wired networks. These models are focused towards node failures while ignoring link failures, and thus are po ...
We study the scaling of the broadcast capacity for a network with a single source and f(N) cooperative relays where N is the number of destinations and f(.) is an increasing function. We consider random extended networks (the network area goes to infinity ...

The throughput of wireless networks is known to scale poorly when the number of users grows. The rate at which an arbitrary pair of nodes can communicate must decrease to zero as the number of users tends to infinity, under various assumptions. One of them ...
In this paper we study the relay-interference wireless network, in which relay (helper) nodes are to facilitate competing information flows over a wireless network. We examine this in the context of a deterministic wireless interaction model, which eliminat ...
