Energy Efficient VLSI Circuits for MIMO-WLAN

Mobile communication - anytime, anywhere access to data and communication services - has been continuously increasing since the operation of the first wireless communication link by Guglielmo Marconi. The demand for higher data rates, despite the limited b ...

Cross Layer Energy-Efficiency Optimization For Cognitive Radio Transceivers

Andreas Peter Burg, Carl Christian Sten Dominic Senning

Designing energy-efficient cognitive radio transceivers requires joint optimization of medium access control and the physical layer implementation. In this paper we show an energy efficiency optimization strategy for IEEE 802.11n compliant transceivers in ...

Performance Analysis of MAC for Power-Line Communications

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

We investigate the IEEE 1901 MAC protocol, the dominant protocol for high data rate power-line communications. 1901 employs a CSMA/CA mechanism similar to – but much more complex than – the backoff mechanism of 802.11. Because of this extra complexity, and ...

Switched Local Schedules for Diamond Networks

Christina Fragouli, Siddhartha Brahma, Ayan Sengupta

We consider a Gaussian diamond network where a source communicates with the destination through

n

non-interfering half-duplex relays. We focus on half-duplex schedules that utilize only local channel state information, i.e., each relay has access to its ...

Simple schedules for half-duplex networks

Christina Fragouli, Siddhartha Brahma

We consider the diamond network where a source communicates with the destination through N non-interfering half-duplex relays. Deriving a simple approximation to the capacity of the network, we show that simple schedules having exactly two states and avoid ...

Simple Relaying Strategies for Half-duplex Networks

Christina Fragouli, Ayfer Özgür Aydin, Siddhartha Brahma

We consider the diamond network where a source communicates with the destination through N non-interfering half-duplex relays. Using simple outer bounds on the capacity of the network, we show that simple relaying strategies having exactly two states and a ...

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 ...

Line and Lattice Networks Under Deterministic Interference Models

Michael Christoph Gastpar, Jasper Goseling

Capacity bounds are compared for four different deterministic models of wireless networks, representing four different ways of handling broadcast and superposition in the physical layer. In particular, the transport capacity under a multiple unicast traffi ...

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 ...

Valuable Detours: Least-Cost Anypath Routing

Martin Vetterli, Matthias Grossglauser, Henri Julien Dubois-Ferrière

In many networks, it is less costly to transmit a packet to any node in a set of neighbors than to one specific neighbor. This observation was previously exploited by opportunistic routing protocols by using single-path routing metrics to assign to each no ...
