Orchestration of smart objects with MQTT for the Internet of Things

Internet is becoming a crucial network on the evolution of humanity. Many companies make available several web services to interact with, permitting users and developers to create custom applications. Meanwhile, devices permit users to remain connected everywhere and anytime. Not only smartphones, tablets and PCs but also washing machines and cars. In this thesis, we will describe a platform which permits the creation of composite services (aka mashups) that combine web services and devicesope

Smart Signs: Showing the way in Smart Surroundings

This paper presents a context-aware guidance and messaging system for large buildings and surrounding venues. Smart Signs are a new type of electronic door- and way-sign based on wireless sensor networks. Smart Signs present in-situ personalized guidance and messages, are ubiquitous, and easy to understand. They combine the easiness of use of traditional static signs with the flexibility and reactiveness of navigation systems. The Smart Signs system uses context information such as user’s mobility limitations, the weather, and possible emergency situations to improve guidance and messaging. Minimal infrastructure requirements and a simple deployment tool make it feasible to easily deploy a Smart Signs system on demand. An important design issue of the Smart Signs system is privacy: the system secures communication links, does not track users, allow almost complete anonymous use, and prevent the system to be used as a tool for spying on users
