Closing the gap in the capacity of random wireless networks

Patrick Thiran, Olivier Dousse

We consider the problem of how throughput in a wireless network with randomly located nodes scales as the number of users grows. Following the physical model of Gupta and Kumar, we show that randomly scattered nodes can achieve the optimal 1/sqrt(n) per-no ...

Optimal Power Control, Scheduling and Routing in UWB Networks

Jean-Yves Le Boudec

Ultra-Wide Band (UWB) is an emerging wireless physical layer technology that uses a very large bandwidth. We are interested in finding the design objectives of the medium access (MAC, namely, power control and scheduling) and routing protocols of a multi-h ...

Rate Performance Objectives of Multi-hop Wireless Networks

Jean-Yves Le Boudec

We consider the question of what performance metric to maximize when designing ad-hoc wireless network protocols such as routing or MAC. We focus on maximizing rates under battery lifetime and power constraints. Commonly used metrics are total capacity (in ...

A stochastic power control algorithm for wireless networks

Ali H. Sayed

In this paper, we propose a power control strategy for distributed wireless networks by using a quadratic state-space control design. Simulation results show the effectiveness of the proposed power control algorithm. ...

Why Max-min Fairness Is Not Suitable For Multi-Hop Wireless Networks

Jean-Yves Le Boudec

We consider the issue of which criteria to use when evaluating the design of a wireless multihop network. It is known, and we illustrate in this paper, that maximizing the total capacity, or transport capacity, leads to gross imbalance and is not suitable. ...

Multiple antennas and representation theory

Mohammad Amin Shokrollahi

Multiple antennas can greatly increase the data rate and reliability of a wireless communication link in a fading environment, but the practical success of using multiple antennas depends crucially on our ability to design high-rate space-time constellatio ...
