- Introduction in wireless technologies, revision of the OSI networking stack and overview of the class applications.
- Reasons for experimenting under real world settings, issues of results credibility when conducting experiments in a simulation environment.
- Research testbeds for experimenting with wireless technologies.
- Variable bitrate video streaming over wireless technologies.
- Techniques and issues for handover among heterogeneous wireless networks.
- Overview and applications of the SCTP protocol as a transport protocol and a comparison with TCP and UDP.
- Quality of Service issues in wireless networks.
- Adaptive modulation and coding schemes in signaling of wireless networks.
- Analyzing the tools for automated experimentation and collection of measurements in experimental platforms.
The purpose of this course is to introduce students on issues that are studied in experiment-driver research in wireless networks. In particular, the class focusses on research issues in every layer of the OSI networking stack, and how these can be studied using the software tools that are taught in the class. The students will get hands-on experience on wireless networking (WiFI) and 4G technologies (WiMAX, LTE) experimenting on a real testbed environment. Some of the topics that will be discussed in the class are the following: QoS provisioning in WiFi and 4G networks, MAC layer protocols, handover between heterogeneous wireless networks (WiFi, WiMAX, LTE), video over wireless, spectral scanning protocols through cognitive radios, rate adaptation, power control and others. The tools that will be used for the study of the mentioned aspects are: OMF Framework, OML Measurement Library, AFFIX, Click Modular Router, GNU Radio
With the successful completion of the course the student should:
- Have comprehended complex concepts of Quality of Service requirements in wireless networks,
- Reasons for handover between heterogeneous wireless networks, as well as the dynamic adaptive streaming of video using variable bitrate and the dynamic modulation and coding schemes of the wireless signal.
- Should know the Open Source tools and techniques used for experimenting under real world settings.
- Be able to distinguish cases of selecting the most appropriate wireless technology, given some quality of service prerequisites.
- Use the experimental tools and the tools for distributed selection of measurements from the experimental testbeds taught in the class, and present his/her results in a user friendly way.
- Analyze and compose complex experiments on several wireless technologies using different topologies.
- Cooperate with his/her coworkers in small teams for the successful preparation and presentation of a project on cutting edge research topics in wireless technologies, by experimenting under real world settings.
