Delay-Tolerant Networks

Course title: Delay-Tolerant Networks

Code: 3ФЕИТ10З022

Number of credits (ECTS): 6

Weekly number of classes: 3+1+1+0

Prerequisite for enrollment of the subject: None

Course Goals (acquired competencies): The student will be enriched with theoretical and practical work and knowledge in the field of Delay-Tolerant Networks (DTNs). They will study the problems with networking in networks tolerant of huge delay and with problems in the connectivity. Analysis of protocols and possible application used in DTNs (sensor networks, space communications, mobile ad-hoc networks). Developing skills in planning and demonizing of DTNs. Moreover, the students will develop simulation models for DTNs.

Total available number of classes: 180

Course Syllabus: Introduction for Delay-Tolerant Networking (DTN). Networking in "stress" and high heterogeneous environments. Asynchronous message sending. Combination of store-and-forward message switching with physical data transmission/receiving.  Medium access control for delay-tolerant services. Quality of service; streaming control. Modeling of telecommunication traffic; modeling of delays and queues; modeling of delay-tolerant queues. DTN protocol stack. Deterministic and probabilistic routing protocols. DTN Security issues. DTN application requirements. Concrete DTN implementations: inter-planetary communications, submarine communications, sensor networks, mobile ad-hoc networks with minimal number of nodes and etc.
