Matrix Pencil for Positioning in Wireless ad hoc Sensor Network
نویسندگان
چکیده
Wireless ad-hoc sensor networks (WASN) are attracting research interest recently because of their various applications in distributed monitoring, communication, and computing. In this paper, we concentrate on the range error problem of WASN positioning algorithms. A new matrix pencil based time of arrival (TOA) positioning method (MPP) is proposed for WASN. The new scheme employs matrix pencil for multipath time-delay estimation, and triangulation for absolute positioning. Simulations in a square-room scenario show that the positioning performance is generally robust to multipath effect and the positioning error is limited to around one meter.

Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...
