November 20, 2018, from 18h30-20h30


This talk will focus on unattended wireless sensor networks (UWSN), a variation of an application of wireless sensor networks. In UWSN, we envision usage of itinerant sink nodes for collection of sensing data in the network, bringing different use-cases and services compared to the traditional sensor network scenarios. We consider security to be a very important aspect in UWSN, as sensed data are delay-tolerant, remaining in the storage of the sensor node until the itinerant sink can collect it. Therefore, the data becomes easily exploitable. To solve this problem, UWSN can utilize data fragmentation, which fragments sensed data to multiple pieces and distributes them in the network, preventing the attackers to exploit the data even if several of the fragments are upended. However, even data fragmentation methods have some problems, such as energy efficiency / how to distribute them / etc. In this talk, I will analyze the importance and effects of the data fragmentation, and then present a method of how to distribute fragments efficiently in a multi-hop manner, with emphasis on energy efficiency and level of security.
