Eline Rietberg won the Best Paper Award at ICOIN

At the 32nd International Conference on Information Networking (ICOIN 2018) in Thailand, Eline Rietberg (a former MSc student at EEMCS) won the Best Paper Award. Her paper is called ‘Analyzing Information Availability in ICN under Link Failures’. The paper resulted from Eline’s graduation project which was conducted at TNO. Co-authors for the paper were Robert Kooij (TNO and parttime professor in the Network Architectures & Services Group), Lucia d'Acunto (TNO) and Hans van den Berg (TNO/UT).

The paper describes information availability in so-called Information-Centric Networks (ICNs). ICN’s facilitate in-network caching, which has amongst others the advantage of providing higher information availability than traditional IP networks. This property is very beneficial in a variety of scenarios, ranging from node mobility to network disruptions and failures. However, a clear understanding of the extent to which information in ICN’s remains available to the users in those scenarios as well as the impact of different ICN design choices (e.g. caching strategy and caching capacity) and network characteristics (e.g. topology) is currently lacking in literature. In order to fill this gap, we have developed an analytical model to study the information availability in ICN’s when network disruptions occur. In particular, this model allows us to compute the probability that, under the occurrence of link failures, users are still able to retrieve the information they are interested in.
