CoCa - IT Platform and Use Cases for the Connected Car Domain

  • Connected Car
  • Internet of Things
  • eXtensible Messaging and Presence Protocol
  • 3rd party services
  • Mobilis


CoCa is a service infrastructure for the Internet of Things (IoT) supporting the development and provision of pervasive services interconnecting real world objects, backend systems and mobile devices in a seamless manner. With a special focus on the connected car domain, the CoCa infrastructure aims for a simplified and cost efficient development of services which consume floating car data sent by cars of multiple manufactures to provide added-value services on mobile or in-car devices. Different to most of the current IoT approaches which mainly focus on the web service technologies or RESTful services or infrastructure is based on the eXtensible Messaging and Presence Protocol (XMPP), a family of protocols standardized by the IETF supporting unified, real-time communication in highly scalable and extensible manner. Two showcases have been developed to demonstrate the capabilities of the service infrastructure. RemoteBot demonstrates the real-time capabilities for message exchange in the implemented platform. The movements of a Lego NXT Robot can be controlled by an Android app and/or a Nintendo Wii Remote. PowerAssistant implements an e-mobility scenario. Electric car drivers can use an Android app to search for charging stations in proximity. Dependent on the current car position and the remaining battery load reachable charging stations are listed or presented on a map. Part of the charging station data are pricing information for charging and special offers like free Wifi access during charging (as charging can take half an hour or even more). Drivers can easily select the most appropriate offer and book a recharge. Both showcases are based on the Mobilis platform reusing its features XMPP communication and service provisioning.
