Intrusion Prevention Framework for Secure Routing in WSN-Based Mobile Internet of Things

The infrastructure of wireless sensor networks (WSN) is structured in an ad-hoc manner and organized nodes reporting the events to the Base Station (BS). A WSN is integrated with smart technologies to develop fast Internet of Things (IoT) communications among different applications. Recently, many researchers proposed their solutions to optimize IoT data transmissions in an energy efficient manner with cost effective support. However, most of the solutions have focused on the design and development of static topologies and overlooked the dynamic structure of mobile sensor nodes. Furthermore, due to limited constraints of sensor nodes with open accessibility of wireless communications medium, data protection against malicious activities need to be redesign with the least network overheads. Therefore, the contribution of this article is to propose an intrusion prevention framework for mobile IoT devices with its integration to WSN so that to provide data security with improved network delivery ratio. The proposed framework is composed of two sub-components. Firstly, non-overlapping and autonomously organized clusters are generated and maintained the clusters' stability based on the uncertainty principle. Secondly, end-to-end secure and multi-hop routing paths are developed based on the blockchain architecture. The simulation results demonstrate a significant improvement when compared to existing solutions in terms of different network metrics.
