Fundamental limits and optimal operation in large wireless networks

Ayfer Özgür Aydin

Wireless adhoc networks consist of users that want to communicate with each other over a shared wireless medium. The users have transmitting and receiving capabilities but there is no additional infrastructure for assisting communication. This is in contra ...

A multi-band PLL based tuning circuitry for the super-regenerative IR-UWB receiver system

Catherine Dehollain, Michel Declercq

The impulse radio-ultra wide band (IR-UWB) signalling format has been an attractive mode for wireless communication in wireless sensor node system. The super-regenerative principle can be used for impulse reception for its inherent advantages. The oscillat ...

Optimal Multiband Joint Detection for Spectrum Sensing in Cognitive Radio Networks

Ali H. Sayed

Spectrum sensing is an essential functionality that enables cognitive radios to detect spectral holes and to opportunistically use under-utilized frequency bands without causing harmful interference to legacy (primary) networks. In this paper, a novel wide ...

Cooperative spectrum sensing via coherence detection

Ali H. Sayed

Efficient and reliable spectrum sensing plays a critical role in cognitive radio networks. This paper proposes a cooperative sensing scheme that detects the existence of a common signal component in the signals received by multiple geographically distribut ...

The Wireless Synchronization Problem

Rachid Guerraoui, Seth Gilbert

In this paper, we study the wireless synchronization prob- lem which requires devices activated at different times on a congested single-hop radio network to synchronize their round numbering. We assume a collection of n synchronous devices with access to ...

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 ...

Secure Neighbor Discovery in Wireless Networks: Formal Investigation of Possibility

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski

Wireless communication enables a broad spectrum of applications, ranging from commodity to tactical systems. Neighbor discovery (ND), that is, determining which devices are within direct radio communication, is a building block of network protocols and app ...

Towards Provable Secure Neighbor Discovery in Wireless Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski

In wireless systems, neighbor discovery (ND) is a fundamental building block: determining which devices are within direct radio communication is an enabler for networking protocols and a wide range of applications. To thwart abuse of ND and the resultant c ...
