Design and Analysis of Hybrid Wireless Mesh Networks for Smart Grids

Smart Innovation, Systems and Technologies, 2013

In this paper the use of a Hybrid Wireless Mesh Network (HWMN) technologies for the smart grid of Advanced Metering Infrastructure (AMI), which enables the collecting of meter data in real-time, was proposed and analyzed. A Google Maps mashup was developed to read the real GIS data from a local utility company and display the locations of the meters and light poles, which can be selected for mounting the WiMAX or Wi-Fi network devices. A NS-3 simulator was developed to simulate the network traffic of meter data collection over the HWMN and to allow us to evaluate different topologies and to see if their capacities are adequate to report all meter values to the data center within one second. The preliminary simplified simulation results show that with the proper antennae selection for the HWMN, it is feasible to collect meter data from hundreds of thousands smart meters within one second.

A wireless mesh communication protocol for smart-metering

2012 International Conference on Computing, Networking and Communications (ICNC), 2012

Worldwide there has been increasing interest over the past few years for so-called "Smart Meters", in academia, governments and in industry. Such smart-metering systems need a way to communicate the collected data reliably and cost efficiently to the back-office for analysis. Several competing technologies exist and are in use world-wide. Meshnetworks have been the winning technology in the USA and Australia for the past two years, and are gaining interest in Europe at the moment due to its reduced costs and increased reliability. In this paper we present and evaluate a real-life implementation of a new routing protocol for use in smart-metering mesh-network grids. The routing protocol we present is designed with both technological constraints and legislative requirements as posed by the application area in mind. Our evaluation of the protocol is based on real-world experience and data collected from real-world devices, in combination with simulation studies of the protocol. Our evaluation shows that the protocol is a robust, reliable solution for communicating collected data in difficult scenarios, showing great resilience against both bit-errors and node-failures.

Modeling and Simulation of a Wireless Sensor Network for Smart Grid Applications, 2018

Recently, the use of Wireless Sensor Networks (WSNs) with Advanced Metering Infrastructures (AMIs) has played a major role in various aspects of today's power distribution grid, especially at the end-user that will be an essential element of the next generation of electrical power grid (Smart Grid). In fact, the extension of advanced technologies to the end-user can be through WSNs that are able to provide ubiquitous communications and low-cost energy consumption control capabilities. In this regard, the current paper presents a WSN based architecture for smart grid applications. A general mathematical model is introduced, and some WSN and Smart Grid standards are discussed, and then an under Matlab M-file based simulation is presented and discussed.

Performance evaluation of Wireless Mesh Network routing protocol for smart grid networks

2015

Recent Advances in Wireless Mesh Networks (WMN) makes it one of the candidate communication technologies for Smart Grid Automatic Metering Infrastructure (AMI) because of its scalability and low cost of deployment. However, its capacity and multi-hoping performance in dynamic environment may not guarantee resilience and packet delivery reliability requirements of AMI. Theoretical and practical studies have shown that the multi-hoping capacity of a mesh network is constrained by increase in the number of nodes and number of hops in the network. In addition traffic requirements for smart meters will further compound WMN multi-hopping issues. In this paper, the performance of WMN when deployed for AMI is carried out using two wireless routing protocols; Hybrid Wireless Mesh Protocol (HWMP) and Optimised Link State Rout protocol (OLSR) in NS-3. Simulation results show that compared to the reliability requirement of AMI, there is need for improving the routing metric for both protocols. Furthermore, The Dynamic Link Exchange Protocol (DLEP) which allows layer 2 link estimation was proposed to enhance the route decision.

Efficiency Network Construction of Advanced Metering Infrastructure Using Zigbee

IEEE Transactions on Mobile Computing, 2019

An advanced metering infrastructure (AMI) consists of a meter data management system, a concentrator, and a meter. Each component can communicate with all other components, through either wired or wireless connections. In an AMI local area networks, various protocols, such as Zigbee, WiFi, and power-line communication, have the potential for used in AMI communication. Of these protocols, Zigbee offers self-constructing networks, low costs, and superior safety levels. Zigbee is adopted as the LAN communication protocol because of these advantages in this study. In a LAN, a concentrator may encounter many emergent situations, any of which might cause the concentrator to lose its network connection function. Consequently, additional time is required for network construction, which tends to reduce the reliability of smart grids with LANs of this type. To solve these issues, this paper proposes fast join process (FJP) and enhanced FJP to shorten the time of Zigbee network construction. The strategy employed in this paper is to let every meter join a specified concentrator. The proposed FJP does not scan unnecessary channels. By simplifying association message exchange, we further propose a new method called the enhanced FJP. Using these methods, not only can message flow be managed easily, but the time of network construction can also be improved.

SMART METERING SYSTEM FOR HOME AREA NETWORK USING ZIGBEE

— ZigBee technology was developed for special wireless networks where Bluetooth & wi-fi technologies are not showing much better results. In wireless personal area networks (PAN) where we need to transmit low data rate information in comparatively large area (10-100 m). A multi-interface ZigBee building area network (MIZBAN) for a smart metering infrastructure (SMI) for high-rise buildings was developed. This leads meter management functions such as Demand Response for smart grid applications. To cater for the high-traffic communication in these building area networks (BANs), a multi-interface management framework was defined and designed to coordinate the operation between multiple interfaces based on a newly defined tree-based mesh (T-Mesh) ZigBee topology, which supports both mesh and tree routing in a single network. To evaluate MIZBAN, an experiment was set up in a two-floor building. Based on the measured data, simulations were performed to extend the analysis to a 23-floor building. These revealed that MIZBAN yields an improvement in application-layer latency of the backbone and the floor network by 75% and 67%, respectively. Index Terms—Smart Metering Infrastructure (SMI), building area network (BAN), multi-interface, smart grid, ZigBee.

Robust Real-time IEEE802.15.4 MAC Protocol in Multi-Hop Mesh Network for Distribution Smart Grid-AMI

2013

The success of Smart Grid will be based on grid- integrated real-time communication between various grid elements in generation, transmission, distribution and loads. Merit to the ZigBee/IEEE802.15.4std low cost, low power, low data rate, short range, simplicity and free licensed spectrum that makes wireless sensor networks (WSNs) the most suitable wireless technology for smart grid applications. This paper focuses at the distribution layer from advanced metering infrastructure (AMI) gateways at the consumer premises to the distribution point where a multi-hop mesh network is built for large coverage data exchange. While beacon-enabled mode is adopted for energy efficient operations, IEEE802.15.4std does not define any mechanisms to enable beacon mode in mesh network. Therefore, in this paper, a modified Zigbee WSN MAC protocol for real-time multi-hop mesh network topology is developed. The protocol performance is evaluated using NS-2 simulation and the preliminary results are encou...
