Capacity Scaling of Cognitive Networks: Beyond Interference-Limited Communication

The capacity scaling laws of two overlaid networks are investigated, which are located in the same area sharing the same wireless resources with different priorities. The primary network can be regarded as an existing communication system operated in a lic ...

Exchanging Pairwise Secrets Efficiently

Christina Fragouli, Suhas Diggavi, Iris Safaka

We consider the problem where a group of wireless nodes, connected to the same broadcast domain, want to create pairwise secrets, in the presence of an adversary Eve, who tries to listen in and steal these secrets. Existing solutions assume that Eve cannot ...

Creating Secrets out of Erasures

Christina Fragouli, Suhas Diggavi, Panagiotis Kostopoulos

Current security systems often rely on the adversary's computational limitations. Wireless networks offer the opportunity for a different, complementary kind of security, which relies on the adversary's limited network presence (i.e., that the adversary ca ...

QUILT: A Decode/Quantize-Interleave-Transmit Approach to Cooperative Relaying

Christina Fragouli, Suhas Diggavi, Siddhartha Brahma, Ayan Sengupta, I-Hsiang Wang

Physical layer cooperation of a source with a relay can significantly boost the performance of a wireless connection. However, the best practical relaying scheme can vary depending on the relative strengths of the channels that connect the source, relay an ...

A Multipurpose Testbed for Full-Duplex Wireless Communications

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pavle Belanovic

Unlike in the traditional half-duplex (HD) mode of transmission over a wireless link, in the full-duplex (FD) mode both terminals receive and transmit on the same frequency band, simultaneously. Hence, FD gives us up to twice the spectral efﬁciency of HD, ...

Attaining optimal batch performance via distributed processing over networks

Ali H. Sayed

This work shows how the combination weights of diffusion strategies for adaptation and learning over networks can be chosen in order for the network mean-square-error performance to match that of an optimized centralized (or batch) solution. The results sh ...

Interference Channels with Bursty Traffic and Delayed Feedback

Suhas Diggavi, I-Hsiang Wang

In this paper we study interference management in wireless networks with bursty user traffic. In each time slot, whether a user is on or off for transmission is governed by its own Bernoulli random state. At each transmitter, the states of activities of ot ...

Multi-Criteria Optimization of Access Selection to Improve the Quality of Experience in Heterogeneous Wireless Access Networks

Laura Toni

Wireless technology is one of the revolutionary ad- vancements providing users with ubiquitous data and telephony access anywhere and anytime without any physical connection. The nowadays deployed wireless networks named WiFi, World- wide Interoperability ...

Cooperative Relaying at Finite SNR–-Role of Quantize-Map-and-Forward

Christina Fragouli, Ayan Sengupta, I-Hsiang Wang

Quantize-Map-and-Forward (QMF) relaying has been shown to achieve the optimal diversity-multiplexing trade-off (DMT) for arbitrary slow fading full-duplex networks as well as for the single-relay half-duplex network. A key reason for the DMT-optimality of ...
