DECENTRALIZED BLOCKCHAIN-BASED TRUST AND SECURITY FRAMEWORK FOR COOPERATIVE MULTIPATH ROUTING IN WSNS AND IOT NETWORKS

Wireless sensor networks (WSNs) and Internet of Things (IoT) networks have applications in smart cities, industrial monitoring, healthcare, and environmental surveillance, but since the networks have open wireless communication, resource constraints, and decentralized architecture, they are very susceptible to security threats such as malicious routing, manipulation of trust, and interference with data. Although cooperative multipath routing enhances fault tolerance and reliability via distributing traffic among more than one path, identifying correct evaluation of trust and ensuring the safety of coordination between the involved nodes are critical factors of success. Currently used trust based routing
