Received Signal Strength (RSS) localization has the attraction of requiring only simple receiver hardware. The basic idea is to find the position estimate that is most consistent with the received signal power measurements observed at multiple known locations in the area of interest. A fundamental assumption is that the signal power measurement is proportional to the product of the reference emitter...
In cognitive radio sensor networks, it is a critical work to localize the location of primary user (PU) for radio resource utilization. Most of received signal strength (RSS)-based PU localization schemes assume that path loss exponent (PLE) is a deterministic. This assumption however is impractical because PLE varies according to time and space in the network. With the motivation, in this paper we...
Wireless sensor networks are being used in a variety of ways — from reconnaissance and detection in military to biomedical applications and a wide variety of commercial endeavors. We introduce a position-adaptive direction finding method using mobile sensor networks and present recent experimental results in localization of a non-cooperative sensor node using static and mobile sensor networks. Electromagnetic...
