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

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

LOADng Routing Protocol Evaluation for Bidirectional Data flow in AMI Mesh Networks

This research work denotes a novel evaluation of LOADng the routing protocol for Wireless Sensor Network. The LOADng protocol implementation is a part of ITU-T G.9903 recommendation based on the framework of the LLN On-demand Ad hoc Distance-vector Routing Protocol - Next Generation (LOADng) proposed by IETF specified by the IETF Internet-Draft draft-clausen-lln-loadng-11 and currently still in its design phase. LOADng is a reactive on demand distance vector routing protocol derived from AODV the Ad hoc On-demand distance vector protocol proposed by IETF. This work was motivated by the need for a novel protocol implementation for smart metering applications providing better performance and less complexity than RPL the Routing Protocol for Low power and lossy networks and adapted to (LLNs) requirements and constraints. Our implementation was successfully integrated into the communication layer of Contiki OS the Wireless Sensor Network operating system and evaluated through extensive simulations for AMI Mesh Networks.

The Enhancement of Communication Technologies and Networks for Smart Grid Applications

The current electrical grid is perhaps the greatest engineering achievement of the 20th century. However, it is increasingly outdated and overburdened, leading to costly blackouts and burnouts. For this and various other reasons,transformation efforts are underway to make the current electrical grid smarter. A reliable, universal and secure communication infrastructure is mandatory for the implementation and deployment of the future smart grid. A special interest is given to the design of efficient and robust network architecture capable of managing operation and control of the next generation power grid. For this purpose new wired and wireless technologies are emerging in addition to the formerly applied to help upgrade the current power grid. In this paper we will give an overview of smart grid reference model, and a comprehensive survey of the available networks for the smart grid and a critical review of the progress of wired and wireless communication technologies for smart grid communication infrastructure. And we propose end to end communication architecture for Home Area Networks (HANs), Neighborhood Area Networks (NANs) and Wide Area Networks (WANs) for smart grid applications. We believe that this work will provide appreciated insights for the novices who would like to follow related research in the SG domain.
