A hybrid ad hoc network is a structure-based network that is extended using multi-hop communications. Indeed, in this kind of network, the existence of a communication link between the mobile station and the base station is not required: A mobile station t ...
The emerging technology of vehicular communications (VC) raises a number of technical problems that need to be addressed. Among those, security and privacy concerns are paramount for the wide adoption of VC. In this position paper, we are concerned with pr ...
In this paper, we consider the problem of detecting and locating buried land mines and subsurface objects by using seismic waves. We demonstrate an adaptive seismic system that maneuvers an array of receivers, according to an optimal positioning algorithm ...
Goal, Scope and Background. Telephony as well as remote data transfer is increasingly performed via mobile phone networks. However, the environmental consequences, in particular of the End-of-Life (EOL) treatment, of such network infrastructures have been ...
Vision--based place recognition is a desirable feature for an autonomous mobile system. In order to work in realistic scenarios, a visual recognition algorithm should have two key properties: robustness and adaptability. This paper focuses on the latter, ...
We are interested in markets which are being restructured or about to be created, as a result of the co-evolution of technologies and market dynamics. A systemic analysis of competition alternatives among groups of firms seems more accurate in order to und ...
Ubiquitous computing is still a maturing field of investigation. The vision of the seamless integration of computers to people’s life has yet to happen, if it ever has to become a reality. Nowadays, most mobile, distributed systems and sensor technologies ...
