An Evaluation of Position Estimate Algorithm in Goods Tracking System using Mobile Detecters

With performance improvement of location technology, location information service at- tracts attention currently. However, there is no system that achieve the goods tracking service. We think the reasons are necessity of high position precision, cost for expanding management range, limitation of management target. We have proposed new location tracking method, "location track- ing method in cooperation with mobile detectors". In this paper, we evaluated the performance of proposed position esitimate algorithms that in the previous paper. I implemented the prototype system and evaluated one of proposed position estimate algorithms. The results indicated a posi- tion becomes high precision by using position esitimate algorithm. Nest, I evaluated performance of position estimate algorithm changed by a defference of a position of goods with the simulation.
