A comparative performance study of the routing protocols RPL, LOADng and LOADng-CTP with bidirectional traffic for AMI scenario

摘要

With the introduction of the smart grid, Advanced Metering Infrastructure(AMI) has become a main component in the present power system. The effectiveimplementation of AMI depends widely on its communication infrastructure andprotocols providing trustworthy two-way communications. In this paper we studytwo routing protocols philosophies for low power and lossy networks (LLNs) andtheir application for a smart metering scenario. This study purposes a detailedevaluation of two routing protocols proposed by IETF the proactive candidatenamely RPL (IPv6 Routing Protocol for Low-Power and Lossy Networks) and thereactive candidate named LOADng (LLN On-demand Ad-hoc Distance vector routingprotocol - next generation) recently proposed as an Internet Draft, still inits design phase and is part of the ITU-T G.9903 recommendation. In the courseof this study, we also implemented an extension version of LOADng namedLOADng-CTP specified by an IETF draft extended with a collection tree forefficient data acquisition in LLNs. We performed checks on control overhead;End to End Delay and Packet delivery ratio for the two protocols related tomultipoint-to-point (MP2P), and point-to-multi point (P2MP) traffic flow in arealistic smart metering architecture.
