Providing group tour guide by RFIDs and wireless sensor networks

Abstract

This paper proposes a new application framework for group tour guiding services based on RFIDs and wireless sensor networks. We consider a sensing field mixed with multiple independent tourist groups, each with a leader and several members. Members of a group will follow the moving path of their leader, but may occasionally roam around randomly on their own interests. Sensor nodes have to track leaders' locations and maintain guiding paths from members to leaders. A member may inquire where his/her leader is, and a leader may "recall" his/her members. We propose a feasible solution to such an application by using existing technologies and off-the-shelf components. A group guiding protocol is presented. The design enables reliable group guiding at low cost and low traffic load. Our prototyping system is reported and system performance is discussed.

Security Visiting: RFID-Based Smartphone Indoor Guiding System

“…At the first stage, we use Wi-Fi-based localization methods [30,31] to guide visitors International Journal of Distributed Sensor Networks to get close to each other when the distance between them is long. At the second stage, Wi-Fi-RFID-combined method [34] is used to shorten the searching time when host and visitor are close to each other. In this line-of-light range, it is quite easy to find each other.…”

“…Chen et al proposed a framework that supports the group guiding service; that is, several members followed the track of a leader in a mixed group by RFIDs and wireless sensor networks [34]. A response mechanism will be built between leader and members, and a group guiding protocol is presented.…”
