Survivability Mapping Strategy for Virtual Wireless Sensor Networks for Link Failures in the Internet of Things

In the case of virtual wireless sensor networks, a link-failure-oriented survivable network mapping algorithm (F-SVNE) is proposed to address issue link failure in underlying network. First, utilizes fast routing strategy and creates backup route set based on multi-path selection reduce delay fault recovery caused by path selection. Second, adopted set. Finally, stage, efficiency reliability are comprehensively considered, with largest survival probability selected from faulty remap affected failure. Empirical results demonstrate that F-SVNE can efficaciously lessen delay, improve long-term average revenue–cost ratio rate.
