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 ...

Understanding and Tackling the Root Causes of Instability in Wireless Mesh Networks

Patrick Thiran, Adel Aziz, David Starobinski

We investigate, both theoretically and experimentally, the stability of CSMA-based wireless mesh networks, where a network is said to be stable if and only if the queue of each relay node remains (almost surely) finite. We identify two key factors that imp ...

Graph-based codes for quantize-map-and-forward relaying

Christina Fragouli, Suhas Diggavi, Ayfer Özgür Aydin, Siddhartha Brahma, Ayan Sengupta

We present a structured Quantize-Map-and- Forward (QMF) scheme for cooperative communication over wireless networks, that employs LDPC ensembles for the node operations and message-passing algorithms for decoding. We demonstrate through extensive simulatio ...

Energy-Proportional and Scalable Networks

Nedeljko Vasic

The power consumption of the Internet and datacenter networks is already significant due to a large degree of redundancy and high idle power consumption of the network elements. Therefore, dynamically matching network resources to the actual load is highly ...

Energy Efficient Offloading of 3G Networks

Jean-Yves Le Boudec, Nikodin Ristanovic

A huge increase in the amount of data consumed by smartphone users is becoming a serious problem for mobile operators. In three years, mobile data traffic in the AT&T's network rose 5000%. The US operators invest 50 billion dollars in their data networks e ...

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 ...

Neighbor discovery with reception status feedback to transmitters

Ramin Khalili

Neighbor discovery is essential for the process of self-organization of a wireless network, where almost all routing and medium access protocols need knowledge of one-hop neighbors. In this paper we study the problem of neighbor discovery in a static and s ...
