Efficiency of the RPL repair mechanisms for Low Power and Lossy Networks

Routing has been considered as one of the most important issues in 6LoWPAN [22] networks. For this reason, the Internet Engineering Task Force (IETF) has proposed a routing protocol called RPL (Routing Protocol for Low Power and Lossy Networks). This paper presents a performance evaluation of the repair mechanisms of RPL with storing mode, using the Contiki simulation environment. Performance metrics of interest are repair time, packet loss and power consumption. We also study the sensitivity of these metrics to network size and node location.
