International Workshop on Extending Seamlessly to the Internet of Things (esIoT-2012) in conjunction with IEEE IMIS-2012. 4th-6th July (Palermo, Italy) co-organized by IoT6 European Project (www.iot6.eu) Publications by IEEE and several special issues and books. Extending Seamlessly to the Internet of Things (esIoT) is an international workshop focused on the integration aspects of the Internet of Things (IoT). The emerging machine-to-machine (M2M) systems should provide transparent access to information and services through a seamless integration into the Internet. On the one hand, the so-called Web of Things aims for direct Web connectivity by pushing its technology down to devices. On the other hand, cost and energy requirements of embedded devices demand efficient protocols and communication patterns, which affect the application layer. This workshop provides a forum to elaborate on ideas and approaches to adapt, extend, or bridge the existing IoT building blocks, such as ETSI M2M, ZigBee, IPv6/6LoWPAN, RFID, and legacy networked embedded systems. In addition, the impact of the IoT on industry, business, and society, including security and privacy requirements, will be discussed.Proceedings of the IMIS-2012/esIoT-2012 will be published by IEEE Conference Publishing Service (CPS).
