Existing cellular networks are centrally managed and require a tremendous initial investment. With the advancement of new wireless technologies, the operators of traditional networks have to face new competition. New technologies make it possible to provid ...
This thesis studies communication and agreement protocols in wireless ad hoc networks from both theoretical and practical perspectives. The last decade has given rise to the rapid growth of wireless telecommunications such as cellular mobile phone networks ...
Wireless networks suffer from a variety of unique problems such as low throughput, dead spots, and inadequate support for mobility. However, their characteristics such as the broadcast nature of the medium, spatial diversity, and significant data redundanc ...
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 ...
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 ...
In this paper, we consider a large scale sensor network comprising multiple, say K, base stations and a large number of wireless sensors. Such an infrastructure is expected to be more energy efficient and scale well with the size of the sensor nodes. To su ...
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 ...
Using wireless mesh networks to offer Internet connectivity is becoming a popular choice for wireless Internet service providers as it allows fast, easy, and inexpensive network deployment. However, security in WMNs is still in its infancy as very little a ...
There is a clear trend of future embedded systems in moving toward wireless, multimedia, multi-functional and ubiquitous applications. This emerges new challenges in the existing solutions on performance, power, flexibility and costs, calling for innovatio ...
The behavior of a given wireless station may affect the communication capabilities of a neighboring one, notably because the radio communication channel is usually shared in wireless networks. In this tutorial, we carefully explain how situations of this k ...
