In this paper, we propose an off-line algorithm calledTRACKIE to estimate trajectories of mobile nodes based onencounter information. This method only assumes reasonablenumber of landmarks and ad-hoc wireless communicationfacility of mobile nodes, and does not rely on multi-hopad-hoc networks nor global positioning system. The methodachieves low-cost estimation of trajectories and providesaccurate solution (the average estimation error was lessthan 40% of the wireless range in simulations). We haveevaluated TRACKIE with Micaz Mote and shown that estimationerror is about 2m in real environments where wirelessrange is about 3m.
