An ICN-based publish-subscribe platform to deliver UAV service in smart cities

Abstract

Intelligent Transportation Systems (ITS) play significant role in the management of traffic congestion in large cities. However, current ITS platforms are not suitable for real-time traffic control mainly due to the facts that 1) the contents are not rich enough to provide detailed information of current transportation network state, 2) there is no sophisticated notification system to alert the ITS platform about major issues in real-time. Unmanned Autonomous Vehicles (UAV) are promising candidates to provide rich content for traffic control systems in large cities and enable real-time notifications, especially when deployed on a platform that is content-oriented. This paper presents a sensor as a service platform to host live content streams (video, data) from a diverse set of input streams including UAVs, city cameras, loop detectors, etc., and to make the data available to a broad range of customers using a novel data dissemination layer. The data-dissemination layer is a content-oriented system based on information-centric networking, a new paradigm that puts content first, and which inherently enables content mobility and content security (through encryption on demand). To support real-time notification, we have implemented publish/subscribe overlay system based on the ICN paradigm. have also conducted live demos with UAVs providing live transportation video data in the system.
