Course ContentsIntroduction to Wireless Computer Networks: Applications of wireless/mobile communications (vehicles, emergencies, business, replacement of wired networks, mobile and wireless devices). Short history of wireless communication
Wireless Transmission: Frequencies for radio transmission – regulations. Signals. Antennas. Signal propagation (path loss, multi-path propagation, shadow fading). Multiplexing. Spread Spectrum. Cellular systems.
Medium Access Control: SDMA, FDMA, TDMA (Fixed TDM, Classical Aloha, Slotted Aloha, Carrier sense multiple access, Demand assigned multiple access, Reservation TDMA, Multiple access with collision avoidance, Polling), CDMA.
Telecommunications Systems: Principles of cellular networks. Cellular network organization. Operation of cellular systems. Mobile radio propagation effects. Handover. Power control. Traffic engineering. GSM (Mobile services, System architecture, Radio interface, Protocols, Handover). 2.5G GPRS (System architecture). UMTS (Releases and standardization, System architecture, Radio interface, Radio access network (UTRAN), Core network, Handover).
Wireless LAN: Infrastructure and ad-hoc networks. IEEE 802.11 (System architecture, Protocol architecture, Physical layer, Medium access control layer, MAC management, Standards (802.11b, 802.11a, and newer developments)). Bluetooth (User scenarios, Architecture, Radio layer, Baseband layer, Link manager protocol, IEEE 802.15).
Broadband Wireless Access Standards: IEEE 802.16 – WiMAX (System architecture, Protocol architecture, Services, MAC layer, Physical layer, IEEE 802.16a differences).
Mobile Network Layer: Mobile IP (IP packet delivery, Agent discovery, Registration, Tunnelling and encapsulation, Optimizations, Reverse tunnelling).
Mobile Transport Layer: Mobility on TCP congestion control mechanisms. Classical TCP improvements.
Laboratory Work/Homework: Perform comparisons and evaluate performance of various issues in wireless/mobile networks through supervised and/or unsupervised laboratory exercises/homework, using computer simulations and/or packet analysis software (The familiarization of computer network simulators and/or packet analysis software has been gained through the ACOE313 course).
