Abstract
Today, the IETF Constrained Application Protocol (CoAP) is being
standardised. CoAP takes the internet of things to the next level: it enables the
implementation of RESTful web services on embedded devices, thus enabling
the construction of an easily accessible web of things. However, before tiny
objects can make themselves available through embedded web services, several
manual configuration steps are still needed to integrate a sensor network within
an existing networking environment. In this paper, we describe a novel selforganisation
solution to facilitate the deployment of constrained networks and
enable the discovery, end-to-end connectivity and service usage of these newly
deployed sensor nodes. By using embedded web service technology, the need
of other protocols on these resource constrained devices is avoided. It allows
automatic hierarchical discovery of CoAP servers, resulting in a browsable
hierarchy of CoAP servers, which can be accessed both over CoAP and
hypertext transfer protocol.
