Formal analysis of a calculus for WSNs from quality perspective

Besides, under the guide of program analysis, in this paper, we propose two analysis approaches for the extended CWQ calculus: 1) We develop a SAT-based analysis to check whether default values can always be available, so that some error configurations (e.g., deadlock processes), caused by unreliable communications in WSNs, will not be reached; 2) We also propose a data-driven probabilistic trust analysis to decouple the probability of receiving the expected input data from the probability of the trustworthiness of the data, so that the overall trustworthiness of the system decision is determined by performing a relational analysis to combine these two probability distributions. Finally, we give a real-world case study with the scenario of refueling a car to demonstrate the applicability of the extended calculus and these two analysis approaches on the extended calculus for WSNs.
