RF Time-of-Flight Locating System for WSNs (Project Information Sheet).
PDF (RF Time-of-Flight Locating System (Project Information Sheet))
Position information of sensor nodes within wireless sensor networks (WSNs) is important in order to make use of the data recorded by the sensors themselves. We prototype an RF TOF locating system using off-the-shelf wireless sensor nodes to evaluate position estimation performance. Operation of this system requires no synchronisation or wired infrastructure between referencing architecture by using our previously developed RF TOF ranging algorithm. Our aim is to meet a position estimation accuracy of +/-0.5m under line-of-sight conditions with low latency (< 2 sec).
