一种车载云计算中自增长失效检测器

To meet the diverse requirements of failure detection in vehicular cloud computing, a new Hierarchical Accrual Failure Detector (HA-FD) based on the architecture of vehicular cloud computing was proposed. HA-FD can meet the requirements of different service qualities of multiple applications simultaneously. In HA-FD, the nodes are grouped by Roadside Unit to implement a hierarchical detection method, and the suspicion level is calculated by direct handling of the heartbeat without any distribution assumption. Experimental results show that the HA-FD decreases the detection relationship of the detection system, so as to reduce the overhead. It avoids the influence of distribution assumption on the detection accuracy. It also improves the detection time by using minimum overhead.
