Indoor location for safety application using wireless networks

Phillip Tomé

This paper presents the indoor positioning research activities carried out within the scope of the Liaison project. Most of the work has been performed on WiFi location. WiFi is nowadays widely deployed in buildings such as hotels, hospitals, airports, tra ...

Secure Positioning in Wireless Networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in wireless networks has been studied mainly in a nonadversarial setting. In this paper, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...

Thwarting selfish and malicious behavior in wireless networks

Mario Cagalj

Security is at the core of any communication system and, in particular, of wireless (radio) networks. In this thesis, we focus on three important security aspects in the framework of wireless networks: selfish (noncooperative) behavior at the Medium Access ...

Secure positioning of wireless devices with application to sensor networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in wireless networks has been mainly studied in a non-adversarial setting. In this work, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...

Network-based wireless location: challenges faced in developing techniques for accurate wireless location information

Ali H. Sayed

Wireless location refers to the geographic coordinates of a mobile subscriber in cellular or wireless local area network (WLAN) environments. Wireless location finding has emerged as an essential public safety feature of cellular systems in response to an ...

Location verification and key management in wireless networks

Srdan Capkun

This thesis is primarily concerned with two security mechanisms for wireless networks: location verification and key management. These mechanisms are potential building blocks in the security architectures of a range of applications. Under location verific ...

Secure Positioning in Sensor Networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in sensor and ad hoc networks has been studied in a non-adversarial setting. We show that most of the proposed positioning algorithms are highly vulnerable to attacks from compromised network nodes and malicious (outside) ...

Secure and Privacy-Preserving Communication in Hybrid Ad Hoc Networks

Jean-Pierre Hubaux, Srdan Capkun

We present a scheme for secure and privacy-preserving communication in hybrid ad hoc networks. Our scheme enables users to secure communication and to protect their anonymity and location privacy. Our approach is based on frequently changing node pseudonym ...

GPS-free Positioning in Mobile Ad-Hoc Networks

Jean-Pierre Hubaux, Srdan Capkun

We consider the problem of node positioning in ad hoc networks. We propose a distributed, infrastructure- free positioning algorithm that does not rely on GPS (Global Positioning System). Instead, the algorithm uses the distances between the nodes to build ...
