PROBLEM STATMENTS

Designing and Deployment using WMN techniques - Challenge Questions

◦Does the WMN meet the network performance requirements for real-time Meter Data Collection?

◦What is the trade-off between the Scalability and the Performance?

APPROACH

Develop a Network Model for Communication Network ◦ It is a Metropolitan Area Network (MAN)◦ We are interested in a Hybrid WMN Architecture

High Scalability Integrated Technologies: 802.11, 802.16 An Important Architecture in the Future

Develop an AMI application: MeterReportingSim◦ To simulate the process of meter data reporting

Simulate the AMI Meter Data Reporting process◦ Develop and Implement the Scenarios in Network

Simulator SW Analyze the Results

◦ Statistical End-to-end Network Performance: Throughput, Delay

◦ Trade-off between Scalability and Performance of network model. Number of WLANs vs. Throughput and Delay Number of Hops vs. Throughput and Delay
