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 ...

Coding schemes for broadcast erasure channels with feedback: the two multicast case

Christina Fragouli, Efe Onaran

We consider the single hop broadcast packet erasure channel (BPEC) with two multicast sessions (each of them destined to a different group of

N

users) and regularly available instantaneous receiver ACK/NACK feedback. Using the insight gained from recent ...

On Self-interference Suppression Methods for Low-complexity Full-duplex MIMO

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pavle Belanovic, Konstantinos Alexandris

Full-duplex wireless communication offers improved spectral efﬁciency, as well as more efﬁcient relaying and medium access, but requires suppression of self-interference. In this paper we analyze the existing methods for active RF suppression and use the ” ...

Design and Energy Management Optimizations for Wireless Sensor Networks

Mitko Tanevski

Real-time monitoring of the temperature in supermarket refrigerators, testing air quality, detecting presence or position of a person indoors, monitoring the structural integrity of bridges, and measuring soil humidity for precision agriculture are only a ...

Building Wireless Network Coding Protocols

Lorenzo Keller

This work studies how to build wireless network protocols that achieve better reliability, lower delay and higher throughput than existing alternatives by using network coding and by exploiting the broadcast nature of the wireless channel. In the first par ...

Development and Evaluation of Multi-Lead Wavelet-Based ECG Delineation Algorithms for Embedded Wireless Sensor Nodes

David Atienza Alonso, Francisco Javier Rincon Vallejos, Nadia Khaled

This work is devoted to the evaluation of multilead digital wavelet transform (DWT)-based electrocardiogram (ECG) wave delineation algorithms, which were optimized and ported to a commercial wearable sensor platform. More specifically, we investigate the u ...

Routing and search on large scale networks

Dominique Florian Tschopp

In this thesis, we address two seemingly unrelated problems, namely routing in large wireless ad hoc networks and comparison based search in image databases. However, the underlying problem is in essence similar and we can use the same strategy to attack t ...

A Randomized Countermeasure Against Parasitic Adversaries in Wireless Sensor Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Jun Luo

Due to their limited capabilities, wireless sensor nodes are subject to physical attacks that are hard to defend against. In this paper, we first identify a typical attacker, called parasitic adversary, who seeks to exploit sensor networks by obtaining mea ...

Erased Secrets: Practical Information-Theoretic Group Secrecy

Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani, Uday Kiran Pulleti

We consider the scenario where a group of wireless nodes want to exchange a secret key, such that no eavesdropper can guess the key. Today, this can be achieved using publickey cryptography, e.g., the Diffie-Hellman or the RSA keyexchange algorithms. Howev ...

Constructing and decoding GWBE codes using Kronecker products

Mohammadjavad Faraji, Pedram Pad

In this letter, we introduce a novel method for constructing large size generalized Welch bound equality (GWBE) matrices. This method can also be used for the construction of large WBE matrices. The advantage of this method is its low complexity for constr ...
