Abstract:
Graceful degradation entails a loss of functionality or reduction in the service quality that a system provides in response to faults. One new form of graceful degradation, which is called region adherence, upper-bounds the violation of safety due to faults in space. Bounding in space means that the decrease of service quality, which the system provides to its environment, is upper-bounded per fault. In this paper, we investigate the effect of composing region-adherent systems such that the resulting system is also region-adherent. We analyze the service quality of region-adherent wireless sensor networks, which are structured according to different topologies. We cover all possible fault scenarios and analyze their impact on differently structured networks by calculating the minimal, the average, the standard deviation, and the variance of the resulting service qualities.
