A Resilient Embedding Framework for Virtualized Wireless Sensor Networks in <scp>IoT</scp> ‐Enabled Environments

ABSTRACT This increasing dogmatism of the traditional wireless sensor network (WSN) systems poses severe problems in dynamic and resource‐bound Internet of Things (IoT) systems. In this paper, a robust virtualization architecture is proposed to facilitate the deployment of virtual communities in IoT‐enabled WSNs, enabling both node‐level and network‐level embedding. The core component of this framework is the ReVNE (Resilient Virtual Network Embedding) algorithm, which maximizes survivability, improves the rate at which virtual network requests are accepted, and reduces recovery delay after network failures have occurred. Large‐scale simulations are used to test this solution and compare it to the existing algorithms, such as N‐SVNE and RLE‐SVNE. Results show that ReVNE is far more effective than current approaches in terms of throughput, latency, fault recovery, and routing overhead, thus providing a robust and scalable solution to virtualized IoT apps.
