“Internet of things” is the interconnection, by means of internet, of different computing devices inserted in regular or physical objects. Dumb physical objects equipped with smart sensors will be capable to accomplish complex tasks that necessitate a great degree of intelligence. These smart objects are therefore able to sense the external environment, collect information accordingly, and share the collected data. The collected information needs to be processed, analyzed and stored in order to deliver values and services to the user. Since, data processing and storage are generally done in a remote server, data needs to be transported from the sensors to the servers.
