Cascading failures of wireless sensor networks

摘要: Despite the fact that research related to invulnerability of wireless sensor networks (WSNs) has made gratifying progress, most it focuses on their topology tolerance but fails consider impact traffic load and energy consumption invulnerability. In this work, we build a cascading model WSNs by considering exhaustion, invalid connectivity overload. We evaluate performance two types WSN models, i.e., scale-free random network ones, when facing failures. The study shows performs better than one. Through evaluation contributions causes node failures, find although is triggering condition for major reason failures in network.
