Dear all, I wanted to ask a couple questions that are aimed at the same end. The objective is to be able to localize mobile sensors when the come in the hearing range of another sensor, for instance, the base station. This is somehow intended for indoor location tracking. Then my questions are the following
1) Is it possible to use TinyOS in order to estimate (with a low error, ie. ~1 meter) the distance between two communicating nodes? My idea is using round trip times but I don't know how accurate this could be due to the processing time of the nodes. 2) Is it possible to reduce the transmission power of sensor nodes so that only a node close can receive the signal? I thought this could possibly be done with the LowPowerListening interface, but having a quick look at the interface I only saw methods related to the duty cycle. Any comments, suggestions or experiences are welcome -- Ruben Rios _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
