The Internet of things (IoT) started to grip traction beyond anyone has imagined. IoT revolves around device-to-device communication and getting billions of devices communicate with each other autonomously in a scalable fashion. IoT is built on cloud computing technologies and networks of real time data-gathering sensors. IoT doesn’t function without cloud-based applications that interpret and transmit data coming from heterogeneous sensors. However, the real value of IoT is not about collecting and analyzing streams of data, but rather on creating innovative techniques and mechanisms that turn this data into actions. The S-IoT workshop is intended to create a platform for researchers, developers, and practitioners in current IoT and ubiquitous computing from academia, industry, and service providers to share and discuss their ideas, experiences, challenges, and practical implementations related to the Internet of Things. We encourage high quality submissions addressing current challenges and proposing novel research directions. We invite technical research papers, industrial papers, position papers, and tool demonstration papers.
