Effect on Network Performance of Common versus Private Acquisition Sequences for Impulse Radio UWB Networks

Jean-Yves Le Boudec, Ruben Merz

Packet detection and timing acquisition for IR-UWB networks such as 802.15.4a relies on the presence of an acquisition sequence (or preamble) at the beginning of each packet. A simple network design choice is to use a common acquisition sequence for the wh ...

Data Management for a Smart Earth: The Swiss NCCR-MICS initiative

Karl Aberer

The Swiss National Competence Center for Research in mobile Information and Communication Systems (NCCR-MICS or MICS) is one of several research initiatives sponsored by the Swiss National Science Foundation to promote long term research projects in areas ...

Three topics in parallel communications

Emin Gabrielyan

The main objectives pursued by parallelism in communications are network capacity enhancement and fault-tolerance. Efficiently enhancing the capacity of a network by parallel communications is a non-trivial task. Some applications may also allow one to spl ...

On the Performance of Clustered Energy-Aware Wireless Networks

Ali H. Sayed

We propose a robust energy-aware clustering architecture for large-scale wireless sensor networks and analyze its performance in terms of throughput capacity and power consumption. The results show that clustered networks can achieve performance improvemen ...

Global Sensor Networks

Karl Aberer, Manfred Hauswirth, Ali Salehi

The availability of cheap and smart wireless sensing devices provides unprecedented possibilities to monitor the physical world. On the technical side these devices introduce several original research problems, many of them related to the integration of th ...

A new relaying scheme for cheap wireless relay nodes

Ramin Khalili

In this paper we will propose a relaying scheme for wireless multi-hop networks. It is based on collaboration of intermediate relays at network layer to forward useful side information in place of dumbly forwarding packets. In our scheme we assume that the ...

Information theoretic bounds 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 ...

A Cross-Layer Design Approach to Enhance 802.15.4

Panagiotis Papadimitratos

The low-power communication in wireless sensor networks can be impacted by severe channel impairments. In this paper, to address this problem and achieve high network goodput, we propose that the medium access control protocol takes into consideration the ...

A Fair Scheduling for Wireless Mesh Networks

Jean-Pierre Hubaux, Naouel Ben Salem

Wireless Mesh Networks (WMNs) represent a new and promising paradigm that uses multi-hop communications to extend WiFi networks: By deploying only one hot spot (directly connected to the Internet) and several transient access points (TAPs), an Internet Ser ...
