| AT77.9019 : Selected Topic: Cross-Layer Design for Wireless Networks 3(3-0) | ||
| Course objectives: | ||
New Heterogeneous services emerging in wireless networks require efficient resource management and Quality-of-Service (QoS) support at all layers of the protocol stacks. As opposed to wireline network, in which QoS can be guaranteed by independently optimizing each layer in the OSI model, in wireless networks there is a strong interconnections between layers, which make the layered design approach inefficient. |
||
| Learning Outcomes: | ||
Introduction to wireless networks and layered architecture, principles of cross-layer design, impact of cross-layer interactions for different architectures: cellular and ad hoc networks, model abstractions for layers in cross-layer design for different architectures (cellular and ad hoc networks), quality of service (QoS) provisioning at different layers of the protocol stack with emphasis on physical layer, medium access control (MAC) and network layers, examples of cross-layer design in the literature: joint optimizations involving beamforming, interference cancellation techniques, MAC protocols, admission control, power control, routing and adaptive modulation. |
