SenseCode: Network Coding for Reliable Sensor Networks

Christina Fragouli, Lorenzo Keller, Emre Atsan

Designing a communication protocol for sensor networks often involves obtaining the right trade-off between energy efficiency and end-to-end packet error rate. In this article, we show that network coding provides a means to elegantly balance these two goa ...

Smashing WEP in A Passive Attack

Serge Vaudenay, Martin Vuagnoux, Pouyan Sepehrdad, Petr Susil

In this paper, we report extremely fast and optimised active and passive attacks against the old IEEE 802.11 wireless communication protocol WEP. This was achieved through a huge amount of theoretical and experimental analysis (capturing WiFi packets), ref ...

Content Management in Mobile Wireless Networks

Francisco De Meneses Neves Ramos Dos Santos

Approximately one billion users have access to mobile broadband, through which they intend to obtain the same data they can reach using a wired connection. Because of the cost of transmitting data over a mobile-broadband connection and given that 3G networ ...

On the Asymptotic Validity of the Decoupling Assumption for Analyzing 802.11 MAC Protocol

Jean-Yves Le Boudec

Performance evaluation of the 802.11 MAC protocol is classically based on the decoupling assumption, which hypothesizes that the backoff processes at different nodes are independent. This decoupling assumption results from mean field convergence and is gen ...

Modeling and Measuring Performance of Data Dissemination in Opportunistic Networks

Nikodin Ristanovic

In this thesis we focus on understanding, measuring and describing the performance of Opportunistic Networks (ONs) and their applications. An “opportunistic network” is a term introduced to describe a sparse, wireless, ad hoc network with highly mobile nod ...

Bringing Stability to Wireless Mesh Networks

Adel Aziz

Wireless mesh networks were designed as a mean to rapidly deliver large-scale communication capabilities without the support of any prior infrastructure. Among the different properties of mesh networks, the self-organizing feature is particularly interesti ...

Secure Neighbor Discovery and Ranging in Wireless Networks

Marcin Poturalski

This thesis addresses the security of two fundamental elements of wireless networking: neighbor discovery and ranging. Neighbor discovery consists in discovering devices available for direct communication or in physical proximity. Ranging, or distance boun ...

Reliable Physical Layer Network Coding

Michael Christoph Gastpar

When two or more users in a wireless network transmit simultaneously, their electromagnetic signals are linearly superimposed on the channel. As a result, a receiver that is interested in one of these signals sees the others as unwanted interference. This ...

Distributed Delay-Power Control Algorithms for Bandwidth Sharing in Wireless Networks

Nicolas Gabriel Gast

In this paper, we formulate a delay-power control (DPC) scheme for wireless networking, which efficiently balances delay against transmitter power on each wireless link. The DPC scheme is scalable, as each link autonomously updates its power based on the i ...

A Measurement-Based Algorithm to Maximize the Utility of Wireless Networks

Patrick Thiran, Julien Pierre Sacha Herzen, Ruben Merz, Adel Aziz

The goal of jointly providing fairness and efficiency in wireless networks can be seen as the problem of maximizing a given utility function. The main difficulty when solving this problem is that the capacity region of wireless networks is typically unknow ...
