Robust Distributed Reprogramming Protocol of Wireless Sensor Networks for Healthcare Systems

Abstract

With the development of the wireless communication technologies, the wireless sensor networks (WSNs for short) are considered as one of the key research areas in healthcare systems. However, there is sometimes a need for removing bugs or adding new functionalities after WSNs are deployed. Wireless reprogramming is a process for propagating a new code image or relevant commands to sensor nodes in WSNs. In this paper, we propose a robust distributed reprogramming protocol of WSNs for healthcare systems, in which the security requirements are proved to be secure based on the elliptic curve discrete logarithm problem, such as existential unforgeability of signature for code image, authenticity of code image, freshness, and node compromised tolerance.

Secure edge computing: An architectural approach and industrial use case

“…All this process will be executed in the edge domain as it is handled by MEG. The distributed operating system is used by, as data is shared among all the AEs, AGs and ANs. EOS has based its assumption on the CAP theorem in which, among three properties (consistency, availability and tolerance of network partitions) two properties are required to be facilitated.…”
