The design and implementation of OMA restful location services in wireless sensor environments

Open Mobile Alliance RESTful location services are standard RESTful web services for terminal location. They are location technology independent, and enable applications´ portability and interoperability. Wireless sensors are electronic devices that can sense context: space, environment, and physiology. Location is a key element of space context information. Wireless sensors can sense location with a level of accuracy that most other technologies cannot provide, which has made them the technology of choice for several applications. This article focuses on the design and implementation of OMA RESTful location services in wireless sensor environments. A novel architecture is proposed and implemented. The architectural components and operational procedures are described. The proof of concept prototype is also described, along with the measurements. Several lessons were learned in this process and are shared in the article.
