A survey on resiliency assessment techniques for wireless sensor networks

Resiliency is becoming one of the most important non functional properties of Wireless Sensor Networks (WSNs), as their adoption is more and more hypothesized in critical application scenarios. Hence, assessing the resiliency of WSN applications, protocols, and platforms is starting to be an import concern for WSN designers and developers. This paper presents the techniques that are currently used in the field of WSN resiliency assessment, categorized as experimental, simulative, analytical and formal techniques. After reporting the state-of-art according to the four categories, the paper discusses research trends, strengths and weaknesses of existing approaches, and concludes with open issues and ongoing challenges.
