Abstract
To manage sensing information such as temperature, humidity and so on efficiently, it is need to use special purpose protocol. In this reason, IETF WG proposed CoAP protocol, and it is on Internet draft. If it is possible to work on a specific protocol, sensor end-nodes and network devices will be managed efficiently. However, end-nodes have restricted resources, it is hard to applying to CoAP protocol directly. In this paper we analyse a CoAP protocol stack for USN. To verify this protocol quickly, at first we implemented CoAP protocol stack over PC environments. After the logical verification, we applied this protocol to the USN environment. To do this, we ported CoAP protocol to Cygwin environment, and proposed solutions for hardware dependencies, and it is verified through experiments.
