The localization of passive targets has been widely investigated in the field of security applications. In such a context, the target is non-cooperative, i.e. transceiver-free and not actively associated to any monitoring system. These constraints make the detection and localization process challenging from the sensing technology viewpoint. Standard solutions adopt dedicated and complex sensors (e...
In this work, the exploitation of wireless systems for non-cooperative target localization and tracking is investigated. The information about wireless links quality is available on most of commercially available network devices and represents the input of the proposed methodology. A real-time probability of presence is generated by means of a learning by example strategy that estimates the unknown...
This paper presents a preliminary assessment of the potentialities of the exploitation of smart antennas in WSNs. The more trivial benefits coming from such an integration are: (a) an efficient spatial management of the radiated energy and (b) an efficient and adaptive reuse of wireless links in order to increase the network throughput and to solve coexistence problems arising from the integration...
