Leveraging IP for Sensor Network Deployment
Ease of deployment has always been seen as a major selling point of wireless sensor networks, yet experience has shown deployment to be difficult. The authors argue that parts of these difficulties have come from the lack of a generic networking layer and of well-tested, generic transport protocols in traditional sensornet deployments. They believe that the use of low-power IPv6 can help by providing node-level addressing, point-to-point routing, and generic well-tested transport protocols. They evaluate the performance of HTTP/TCP and CoAP/UDP over a duty cycled radio layer, showing that with a small modification to the duty cycling layer results in a dramatic improvement in performance at a retained low power consumption.
