IEEE802.16 Network Simulation With Mobile Users: Base Station – Project Goal & Scope Studying of the IEEE802.16 standard. Studying of the open source OMNeT++ network simulator. Implementing the IEEE802.16 MAC layer. Collection and analysis of statistical information. Multiple Base Station. Multiple Subscriber Stations (SS). Support for Static & Mobile SSs. Roaming. מטרת הפרוייקט - למדנו את הסטנדרט, את הסימולטור. מימשנו את שכבת ה- MAC, אספנו וניתחנו את הסטטיסטיקות שהתקבלו. היקף הפרוייקט – מימוש תחנת בסיס יחידה. התממשקות עם הרבה משתמשי קצה. תמיכה במשתמשי קצה סטטים ודינמיים. ניידות משתמשים.

Base Station – Design The CS modules handle entry-level processing, converting packets to and from IP format. The CPS is the Central Processing System. It contains the various sub-modules that will handle the data processing and scheduling. IP CS-PDU/ MSDU PHY Frame PHY Frame IP CS-PDU/ MSDU

Modulation Chart Basic modulation is QPSK. All management information passes in this modulation. 5 Next we have more advanced modulations, 16QAM and 64QAM. 10.5 16 QPSK 16QAM SNR 64QAM Further sub-divisions of these modulations include error-correction code implementation.

Traffic Simulation Support is implemented for a diverse range of connection simulation. They range from application-specific data to VoIP. Each data type has its own QoS requirements. Further data types can be easily added into the database, and the BS scheduler can be changed to accommodate this change. The system is fully modular.

Results - Statistics Collecting Currently only Throughput and Average Delay are implemented. Further statistics collecting support will be added in the near future.

What Have We Learned? The 802.16 standard, from the general outline to the particulars of design and implementation. Familiarization with the OMNeT++ network simulation platform, and simulation building in general. Working as part of a team on a (relatively) large-scale project.
