Simulation and Analysis of Wireless Mesh Network In Smart Grid /

Advanced Metering Infrastructure

Philip Huynh

Introduction

• The need to collect metering data in real-time• Challenges in Design and Deployment AMI

Infrastructure using WMN:– How to evaluate the network performance: hundred

thousands of meter, complicated architecture– Design Optimization: trade-off between scalability and

performance properties• Goals– Develop a methodology to evaluate the performance

of WMN in smart grid / AMI

Research opportunity• Academic researches provides the nominal

evaluation of the performance of WMN. For example:

• Commercial products in the smart grid field has not supported the real-time metering data collection. An important issue causes low performance in their WMN is the network architecture.

• Research Opportunities: – WMN architecture: high performance, low cost– Methodology for evaluating the performance of WMN in

real-time metering data collection

Approach• Develop a Network Topology Planning Tool

– Visually planning the antennae mounting place of network devices– Statistical data about residential density to support network design

• Develop a Network Model for AMI Communication Network – It is a Wide Area Network (WAN)– We are interested in a Hybrid WMN Architecture

• High Scalability• Integrated Technologies: IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX)• An Important Architecture in the future

• Simulate the network model and Analyze the results– Implement the simulator in the simulator platform, for example NS-3– Simulate many experiments on the network simulator: WAN, MAN, NAN, LAN– Analyze the simulation results to evaluate the network performance, i.e.

Throughput, Delay– Evaluate the trade-off between Scalability and Performance of network model

SG-WIP Planning Tool

• Visually planning the Antenna mounting place for the WiMAX/Wi-Fi WMN– This is a mashup that overlays the Wireless

Infrastructure, GIS data (street light poles, housing units) on the Google Maps.

• Export the network topology as file for further research

• Can be integrated to the network simulator

SG-SIM Simulator

• Implement the proposed hybrid WiMAX/Wi-Fi Network Model in NS-3 Platform

• Parameters of the Simulator– Network types: WAN, MAN, NAN, LAN– Number of nodes, Transmission Rate– Others: network initialization time,…
