A seminar will comprise of one lecture delivered by the seminar instructor followed by an instance with student presentations. Each student selects one seminar for presentation. All students are welcome to attend all seminars but are only expected to give one presentation. Attending and presenting in one seminar is mandatory to pass the course. The topics for the student presentations will be discussed and assigned at the end of the first seminar meeting. The presentation is preferably prepared by a team of two students. The instructor will recommend some references for the presentation and the presentation should last about ten minutes with 5 minutes for discussions. There will be a PC projector available.
The following advanced topics in wireless mobile networking will be offered in the form of seminars. (Check the schedule for time). Signup for a seminar by sending an email to the main instructor with your first and second preference.
- A: Wireless sensor networks (Instructor: Luca Mottola, SICS), April 20, 08-10 (Pol_1245) and April 22, 08-10 (Pol_1245);
Recent advances in micro-electromechanical systems, embedded computing and wireless communications are converging towards future wireless miniature sensor systems. Smart and cheap micro sensor devices, ranging in size from cubic inches to cubic millimeters, each having multiple on-board miniaturized low-powered sensors can be deployed in small and large numbers (up to thousands) to instrument new scientific and societal applications: monitoring temperature, early detection of natural disasters like forest fires, monitoring pollution levels, detecting structural flaws and wildlife tracking, to name a few. Designing sensor networks opens up many research questions, e.g., localization, energy-efficiency, resource management, diffusion of sensor data, designing system software that fits in the limited memory.
- B: Delay- and Disruption-tolerant networks (Instructor:Christian Rohner), April 26, 08-10 (Pol_1245) and May 3, 15-17 (Pol_1245);
There are many harsh and challenging environments, for example, deep space communication, digital content delivery in rural areas with under-developed infrastructure, wildlife and habitat monitoring, where communication network are typically characterized by disruption of communication links leading to frequent and long durations of network partitioning, long delays, limited resources and heterogeneity. Traditional networking solutions (based on TCP/IP) are not viable and even extensions such as ad hoc networking do not provide a definite solution since they need a reliable end-to-end path between a source and destination. Delay- an disruption-tolerant networking (DTN) is emerging as a solution for these challenging network environments. This area is relatively new and there is ongoing research to address open questions regarding the network architecture, data transport, routing and forwarding, and congestion control, to name a few.
- C: Applications over wireless mobile networks (Instructor: Per Gunningberg), April 16, 10-12 (Pol_1245) and 27 April, 15-17 (Pol_1245);
The unpredictable nature of the wireless channel and device mobility poses many challenges for real-time applications such VoIP and video streaming, as well as for reliable data services based on TCP. In this seminar we will address these challenges in different wireless networks (e.g., WiFi, Bluetooth, Cellular networks) and consider some of the solutions for quality of service provisioning and improving performance of data transport protocols such as TCP in these networks.
