"Key Challenges in Cloud Computing to Enable Future Internet of Things" is the title of the talk about future Internet of Things that I gave today January 19th at The 4th EU-Japan Symposium on New Generation Networks and Future Internet. The talk provides an architectural view of Internet of Things from the perspective of cloud computing, defines its main requirements for the underlying processing infrastructure, and describes the challenges in cloud computing that should be addressed to meet these requirements. The talk concludes with the description of the instruments that should be used to maximize the value of research and to support the collaboration between Japan and the European Union, namely openness, standards, coordination with running initiatives, and code re-use.
