Description: The course focuses on the key enabling technologies for wireless and mobile networks and delineates their fundamental operating principles. In the first part, the course examines the dominant technologies in the field of wide area and metropolitan area infrastructured networks such as LTE and WiMAX. Then, the course focuses on ad hoc networks, such as Mobile Ad Hoc Networks (MANETs) and opportunistic networks, as well as on Delay Tolerant Networking (DTN). Finally, the course discusses key technologies proposed in the context of 5G networks. Summarizing, the following technologies will be examined during the course:
