Traffic Cam Sharing Traffic Information based on Dynamic ipv6 Multicast Group Assignment using Smartphone Sensors
Recently, a wide variety of location-based services has been developed. In the ﬁeld of intelligent transport systems (ITS), a roadside infrastructure may provide traffic information to vehicles in the area. Exchanging traffic information among nearby vehicles is one of the communication scenarios in the ﬁeld of intelligent transport systems (ITS). An important question in this scenario is”How can traffic information be delivered to only one subset of nearby vehicles in the same road traffic situation?”, for example, to only congested traffic in a certain lane. In this demonstration, we propose a dynamic IPv6 multicast group assignment mechanism using GPS, an accelerometer and a magnetometer embedded in smart phones. Our mechanism enables each vehicle to ﬁnd the relevant vehicles, and to compose a temporary IPv6 multicast address. Our mechanism can deliver traffic information to a group of vehicles in a particular situation. This demonstration, carried out on virtual traffic congestion, shows an information-sharing scenario using a prototype of the proposed mechanism, implemented as an Android application called TrafﬁcCam. Our application demonstrates the usefulness of the proposed mechanism.
