6LoWPAN based service discovery and RESTful web accessibility for Internet of Things

6LoWPAN being one among the enabling technologies of the vision, Internet of Things, brings forward the sensor networks into the world of Internet through the effective implementation of IPv6 on constrained devices. Even then, inorder to avail the numerous services provided by the sensor networks ubiquitously and with ease, there is a need to be cognizant of the available services, identity of nodes providing the desired services and the means to access. In this paper, we present an 6LoWPAN based architecture of sensor/actuator nodes, that employ Simple Service Location Protocol(SSLP), and respond to all service related queries from the user devices. The system implements Constrained Application Protocol(CoAP) a RESTful Architecture to leverage service access similar to HTTP transactions. The proposed architecture also integrates various protocols, defined specific to the constrained LoWPANs like, Neighbor Discovery(ND) Protocol, and Routing Protocol for Low power lossy networks(RPL) for interactions between traditional IP networks and the 6LoWPAN network.
