Big data analysis and IoT

With the recent advances in radio-frequency identification (RFID), low-cost wireless sensor devices, and Web technologies, the Internet of Things (IoT) approach has gained momentum in connecting everyday objects to the Internet and facilitating machine-to-human and machine-to-machine communication with the physical world. IoT offers the capability to connect and integrate both digital and physical entities, enabling a whole new class of applications and services, but several significant challenges need to be addressed before these applications and services can be fully realized. A fundamental challenge centers around managing big IoT data, typically produced in dynamic and volatile environments, which is not only extremely large in scale and volume but also noisy and continuous. This entry discusses characteristics of IoT data, potential applications in IoT, and open research issues for IoT data management.
