RPL (IPv6 Routing Protocol for Low Power and Lossy networks) is a routing protocol recently standardized by the IETF. RPL has been designed to operate in energy-constrained networks with thousands of nodes, and therefore it is one of the most promising candidate routing protocols for Advanced Metering Infrastructure (AMI) networks. In this paper a performance evaluation of RPL is presented. An extensive study of the protocol is carried out with particular focus on Trickle, the algorithm adopted to control routing update distribution across the network. The performance of the protocol is analyzed considering different Trickle parameters in order to capture their impact on route formation and node power consumption. Results highlight that the nondeterministic nature of Trickle can lead to sub-optimal route formation especially when high message suppression is per-formed. In order to mitigate this issue, an enhanced version of the protocol, namely Trickle-F, is proposed in order to guarantee fair broadcast suppression. Trickle-F is demonstrated to be effective in obtaining more efficient routes with the same power consumption of the original version.
