This paper presented a simple delay domain pathloss model that focused on the first and the strongest paths for ranging purposes. This model is capable of simulating effects of the system bandwidths and the center frequencies by following the band plan of the IEEE802.15.4a-2007 standard. Differences of the first and strongest paths were also modeled in the delay and the power domains. A complete model...
Accurate ranging is one of the most promising applications of ultra wideband radio in sensor networks. Amongst variety of ranging methods, threshold-based ranging is a primitive, but robust technique suitable for battery-limited systems. This contribution reports the performance of two threshold-based ranging methods: leading edge detection and search back method. The evaluation utilized real-world...
