Guiding Users to Shops Using the Near-Field Communication between Signages and Mobile Terminals

摘要

This paper proposes two algorithms for navigating users to their destinations using near-field communication between their mobile terminals and digital signage units in an underground area where GPS is not usable. One algorithm focuses on the angle to the destination while the other looks at the distance to the destination. The paper also proposes an algorithm for avoiding traffic congestion by limiting the number of mobile terminals that communicate with a signage unit simultaneously. We have built an underground mall model on a simulator, and evaluated the algorithms in terms of the rate of successful arrival at the destination and the time it takes to reach the destination.
