Graduate standing and this is basically a content self-contained class or consent of the instructor. An introduction-level class on "Computer Networks" and basic C++ programming may help.


Course Description:


This graduate course provides an in-depth study of principles, architectures, protocols, and modeling techniques for mobile wireless networks. The course aims at equipping graduate students with not only a solid foundation and the state-of-the-art knowledge in a wide spectrum of wireless communications techniques and protocols, but also the rigorous analytical capabilities to evaluate the performance of complex mobile wireless systems and networks. As a research-oriented class, this course will also introduce students to the emerging and hot topics in mobile wireless networking and mobile computing research.


The course will start with an introduction of the fundamental architectures and principles of mobile and wireless networks and their relationships with the backbone Internet. The focus will then move on to the main wireless communication theories and modeling techniques used in mobile wireless networks. This is followed by the detailed examinations of a number of most recently developed mobile wireless networking technologies and architectures. Several types of widely employed mobile wireless networks and research topics are investigated in-depth as the further applications of the newly developed wireless networking techniques. The course material consists primarily of the classic and recent technical papers published on major wireless/wired networking journal and conferences and the referenced (recommended, but not required) text books.


The course also aims at introducing new graduate students to research, as well as exploit potential topics for MS comprehensive projects and PhD research directions.

Resources for ns-2:


Ns-2 is a well-known open-source discrete event simulator for networking research, which is an object oriented program written by C++/OTCL. Ns-2 provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless networks. We will use ns-2 for the project for this class.
