Ubiquitous Sensor Network in the NGN Environment

Abstract

Ubiquitous Sensor Network (USN) is a conceptual network built over existing physical networks. It makes use of sensed data and provides knowledge services to anyone, anywhere, and at any time, and where the data is generated by using context awareness. USNs and smart wearable devices are emerging rapidly providing many reliable services facilitating people life. Those very useful small end terminals and devices require a global communication substrate to provide a comprehensive global end user service. In 2010, the ITU-T provided the requirements to support USN applications and services in the Next Generation Network (NGN) environment. One of the main promising domains for the USN application and services is the e-Health. It provides continuous patients monitoring and enables a great improvement in medical services. On the other hand, Vehicular Ad-Hoc NETwork (VANET) is an emerging technology, which provides intelligent communication between mobile vehicles. Integrating VANET with USN has a great potential to improve road safety and traffic efficiency.
