A smarter toll gate based on Web of Things

The Internet of Things perceives a world where-in the embedded devices are made intelligent and can be uniquely identified in the internet. The communication among these devices is achieved by fully integrating them to the web paving way for the concept of Web of Things. With standards like 6LoWPAN at the network layer and 802.15.4 at the physical layer, applications built over these are made smarter, interoperable, scalable and secure. We present a heuristic approach by which interoperability can be implemented at the application layer addressing the issues in a real-time traffic scenario. A REST based design provides loose coupling and lightweight implementation of web services aiding the role of memory constrained devices in the Web of Things. This paper also enlists an efficient publish subscribe mechanism for event notification among the sensors.
