An Architecture for Wireless Simulation in NS-2 Applied to Impulse-Radio Ultra-Wide Band Networks

Jean-Yves Le Boudec, Ruben Merz, Jörg Widmer

We present an architecture for implementing a wireless physical layer in a packet-based network simulator. We integrate this architecture in the popular ns-2 network simulator and use it to implement an impulse-radio ultra-wide band (IR-UWB) physical layer ...

On the throughput scaling of wireless relay networks

Patrick Thiran, Olivier Dousse

The throughput of wireless networks is known to scale poorly when the number of users grows. The rate at which an arbitrary pair of nodes can communicate must decrease to zero as the number of users tends to infinity, under various assumptions. One of them ...

Mobility in wireless networks: friend or foe

Jun Luo

Wireless networking technologies allow computing devices to move while keeping them online, but the device mobility poses considerable technical challenges. Network designers, on the one hand, consider mobility to be harmful because it leads to dynamic and ...

Wireless sensor networks: Enabling technology for ambient intelligence

Carlotta Guiducci

Wireless sensor networks are one of the most rapidly evolving research and development fields for microelectronics. Their applications are countless, and the market potentials are huge. However, many technical hurdles have to be overcome to achieve a wides ...

Energy efficient medium access control for wireless sensor networks

A wireless sensor network designates a system composed of numerous sensor nodes distributed over an area in order to collect information. The sensor nodes communicate wirelessly with each other in order to self-organize into a multi-hop network, collaborat ...

Managing Heterogeneous Wireless Environments via Hotspot Servers

Giovanni De Micheli

Wireless communication today supports heterogeneous wireless devices with a number of different wireless network interfaces (WNICs). A large fraction of communication is infrastructure based, so the wireless access points and hotspot servers have become mo ...

A cross-layer design of wireless ad-hoc networks

We consider a cross-layer design of wireless ad-hoc networks. Traditional networking approaches optimize separately each of the three layers: physical layer, medium access and routing. This may lead to largely suboptimal network designs. In this work, we p ...

Rate Performance Objectives of Multi-hop Wireless Networks

Jean-Yves Le Boudec

We consider the question of what performance metric to maximize when designing adhoc 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 ...
