Experiment-based approach to understand delay tolerant network

Abstract

Dissemination of information in challenged environments such as place with nonavailability of cellular services, post-disaster situations, remote place, disruption min network is often a difficult task. This is due to lack of traditional communication channel which equires end-to-end path to deliver the information using store-forward approach. However, Delay Tolerant Network (DTN) can be useful in such challenging environments as it works even when end-to-end path ceases to exist in the network. It follows store-carry-and-forward approach which incorporated with human mobility can enhance the communication opportunities. Hence, in this thesis a smartphone application called Bluetooth DTN app is developed based on the DTN concept. The experiment is conducted to study how a smartphone based DTN setup would function and how can the use of DTN be justified for challenged environments. Similar scenario is created in Opportunistic Network Environment (ONE) simulator, a widely used simulator to study DTN among the research community to verify the results.
