Course Description:

Wireless and mobile networks experienced a continuous growth during the last years and are expected to provide more and more services in the near future. Development of wireless communication systems requires solving several challenging problems. This course covers both theoretical issues related to wireless networking and practical systems for both wireless data networks and cellular wireless telecommunication systems. Students will also work on a project that addresses some recent research issues in wireless and mobile networking.

 

 

The course will cover the following topics:

·        Overview of the wireless environment and wireless communication systems: slides,

·        Fundamentals of radio communications: radio-waves propagation characteristics, channel models: slides, references

·        Modulation, channel coding, channel estimation, etc. slides(ps), slides(.pdf) , references

·        Channel multiple access schemes for wireless networks (e.g., FDMA, TDMA, CDMA, SDMA), and medium access control schemes for wireless networks.

slides( .ps) , slides(1 slide per page .pdf) , slides(4 slides per page .pdf)

·        Wireless internet: wireless local area networks (e.g., IEEE802.11, Hiperlan2, Bluetooth), routing in multi-hop Ad-hoc wireless networks (e.g., TORA, DSR, DSDV), mobile IP, and TCP improvements for wireless links slides(.ps)

·        Cellular telecommunication systems: second generation systems (GSM, IS95, IS54), and third generation systems (EDGE, CDMA200, WCDMA) slides (.ps)

·        Quality of service in the context of wireless networks: adaptive radio resource management (planning, dynamic/static - distributed/centralized frequency/time-slot/code allocation, adaptive coding), and power saving. Slides1 (.pdf)  Sildes2( .pdf)
