During this internship, I have completed a technical watch on M2M and built a multi-services demonstrator.Concerning the technical watch on M2M platforms, I have compared various M2M solutions under common criteria. A presentation of the main standards and protocols has also been realized. I have worked with my tutor to find a methodology to compare two M2M solutions. A detailed comparison between a internal product and Plat-One has been realized as an example. This technical watch helps the readers to have a global understanding of the M2M world. During this work, I have gained much experience and competence on the collection, organization and analyze of information.Concerning the multi-services demonstrator, I have done the conception (use cases and functional specifications), the development of applications and the integration of all components. At last, a demonstrator was accomplished on a laptop with the ability to be easily deployed on other servers. This work permits to illustrate the features of the platform and the standard ETSI M2M. During this work, I have gained much experience on the development Java and other technologies. Finally, this first approach of the standardization and project management will help me in the future.
