Heterogeneous resources can be aggregated and abstracted according to tailored thing-like semantics, thus enabling Things as a Service paradigm, or better a \u201cCloud of Things\u201d. In the Future Internet initiatives, sensor networks will assume even more of a crucial role, especially for making smarter cities. Smarter sensors will be the peripheral elements of a complex future ICT world. However, due to differences in the \u201cappliances\u201d being sensed, smart sensors are very heterogeneous in terms of communication technologies, sensing features and elaboration capabilities. This article intends to contribute to the design of a pervasive infrastructure where new generation services interact with the surrounding environment, thus creating new opportunities for contextualization and geo-awareness. The architecture proposal is based on Sensor Web Enablement standard specifications and makes use of the Contiki Operating System for accomplishing the IoT. Smart cities are assumed as the reference scenario.<\/jats:p>","DOI":"10.1186\/1687-1499-2012-247","type":"journal-article","created":{"date-parts":[[2012,8,8]],"date-time":"2012-08-08T16:39:54Z","timestamp":1344443994000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":179,"title":["Combining Cloud and sensors in a smart city environment"],"prefix":"10.1186","volume":"2012","author":[{"given":"Nathalie","family":"Mitton","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Symeon","family":"Papavassiliou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Puliafito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kishor S.","family":"Trivedi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2012,8,8]]},"reference":[{"key":"480_CR1","unstructured":"[http:\/\/www.datamation.com\/cloud-computing\/7-hot-cloud-computingtrends-for-2012-1.html]"},{"key":"480_CR2","unstructured":"The Top 10 Smart Cities On The Planet. http:\/\/www.fastcoexist.com\/1679127\/the-top-10-smart-citieson-the-planet"},{"key":"480_CR3","unstructured":"Sensing troubled waters in a Smarter City. http:\/\/www.ibm.com\/ibm100\/us\/en\/service\/grants\/centennialgrantindianinsttech2011.html"},{"key":"480_CR4","unstructured":"Sensor Web Enablement ,Sensor Web Enablement. 2011.
