Security and Cooperation in Wireless Networks

Jean-Pierre Hubaux, Levente Buttyan

According to most technology pundits, progress in wireless and sensor networks will lead us into a world of ubiquitous computing, in which myriads of tiny, untethered sensors and actuators will communicate with each other. Information technology will thus ...

A 58mW 1.2 mm 2 HSDPA Turbo Decoder ASIC in 0.13 μm CMOS

Andreas Peter Burg, Qiuting Huang

This paper presents the implementation of the 1.2 mm2 HSDPA turbo decoder ASIC in 0.13 mum CMOS achieves a measured maximum frequency of 246 MHz, which translates to a maximum throughput of 20.2 Mb/s at 5.5 iterations. The peak throughput of 10.8 Mb/s requ ...

REACA: An Efficient Protocol Architecture for Large Scale Sensor Networks

Ali H. Sayed

The emergence of wireless sensor networks has imposed many challenges on network design such as severe energy constraints, limited bandwidth and computing capabilities. This kind of networks necessitates network protocol architectures that are robust, ener ...

Hierarchical Routing over Dynamic Wireless Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

Dynamic networks are those where the topology changes over time and therefore efficient routes need to be maintained by frequent updates. Such updates could be costly in terms of consuming throughput available for data transmission, which is a precious res ...

Modelling the IEEE 802.11 protocol in wireless multi-hop networks

Mathilde Durvy

IEEE 802.11 is probably the most widely used, medium access control protocol in current wireless networks. In the Wireless LAN (i.e., single-hop) setting, its performance is by now quite well understood. However, in the multi-hop setting where relay nodes ...

Distributed MMSE Relay Strategies for Wireless Sensor Networks

Ali H. Sayed

A fundamental task in a wireless sensor network is to broadcast some measured data from an origin sensor to a destination sensor. Since the sensors are typically small, power limited, and low cost, they are only able to broadcast low-power signals. As a re ...

Efficient and Robust Secure Aggregation for Sensor Networks

Karl Aberer, Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski, Parisa Haghani

Wireless Sensor Networks (WSNs) rely on in-network aggregation for efficiency, however, this comes at a price: A single adversary can severely influence the outcome by contributing an arbitrary partial aggregate value. Secure in-network aggregation can det ...

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 ...
