Bounding Degrees on RPL

RPL is an open routing protocol standardized by the ROLL group of IETF for constrained IP smart objects. It is one of the emergent protocols dedicated for Low Power and Lossy Networks (LLNs). Unfortunately, RPL su↵ers from significant packet loss due to the instability of the routes, and from a poor updates. Most of the existing solutions dedicated to solve the routes instability are based on improving the metrics used for constructing the routes. Generally these metrics are based on some evaluation of the radio link quality. In this paper, we adopt a new approach for addressing route instability in RPL, by placing an additional constraint on the maximum number of children a node can accept during tree construction. We call our solution Bounded Degree RPL (BD-RPL). BD-RPL addresses the absence of updating in the downward routes construction. Technically, we use the existing control messages provided by RPL for bounding the node degrees, as well as for updating the downward routes. ...
