An Active Fault Diagnosis Algorithm Based on Random Walk Approach for Space Information Network

摘要

In this paper, we propose an active fault diagnosis algorithm based on random walk approach under the Space Information Network (SIN) circumstance. Space information network is much more different with wireless sensor network for its long time delay and its inconstant topology. Therefore the existed fault diagnosis algorithm do not have a perfect performance as we want. The algorithm proposed in this paper, we gather information by random walk approach actively and use compressive sensing approach to deal with signal. Through the simulation we can argue that under the space information network circumstance we can handle the problem much more effectively.
