Sámi Network Connectivity
MSc Projects (examensarbeten): E-mail and web caching for DTN
Sámi Network Connectivity (SNC) addresses the issues of connectivity in communications challenged areas and of building together present standards based technology and the evolving delay tolerant technology into functioning networks. The unique feature of SNC as a DTN system is that it is designed to utilize a mix of fixed and mobile gateways in which the routing between systems is based on probabilistic patterns of connectivity. The background is a request from future users, a community of reindeer herders who part of the year operate within Laponia in Northwest Sweden. SNC documents are available at www.snc.sapmi.net. IRTF documents for architecture and other issues of Delay Tolerant Networking: www.dtnrg.org.
The first, basic case of how to send email out of a DTN has been solved in SNC. The thesis should result in a system capable of delivering email, in both directions, between a DTN network and the Internet. Once a good approach has been determined, prototype software should be developed. The software shall be capable of operating in a DTN network running the code DTN2, see www.dtnrg.org. The student for this project you should do system programming well and have the ability to dive into somewhat esoteric matters (sendmail and uucp) and figure it out.
Web caching
Considering the many options for web content, web caching for DTN is a many folded issue. Starting point would be making a bundle. Probably this starts with finding what to put in the bundle, through performing a syntactic analysis of HTML, and recording what the program does as it assembles and renders the page. This MSc project will rely on a principal analysis by Elwyn Davies, U.K. The student will work in parallel to advanced research which may interact with the project process.
