Holistic Trust Management Protocol for Ubiquitous and Pervasive IoT Network

Abstract

Internet of things (IoT)unleashes advanced, intelligent and innovative services to human being to change their life through various application domains. Besides, IoT is new paradigm in emerging communication and information technology came to forefront in recent years draws the attention of researchers and industries to make significant contribution on different applications ranging from smart home automation, healthcare, retail, shipping, banking to smart grid. Despite its widespread presence, current researches lack in recognizing appropriate trust model which has inadequacy of addressing IoT network requirements, user concerns of security, privacy of data transmission, and also resistant of trust related attacks, therefore aforementioned pitfalls lead to notion of proposing our holistic trust management protocol in this paper to deter attacks cropping up inside ubiquitous and pervasive network of IoT fundamental infrastructure known for the characteristics of interoperability, dynamicity, and heterogeneity. In this paper we proposed dynamic trust mechanism to enhance trust between participating entities to establish communication for sharing services or resources and further, shun the attacks launched by malicious/intruder nodes only aim is to inhibit the communication inside network. Our fuzzy logic-based trust scheme approach fused into trust evaluation process of nodes and later, decision making based on degree of trust result identifies the malicious nodes. We simulated our approach considering different parameters on network simulator selecting relevant test devices and the result of which shows our proposal simulation figures out performing the existing trust models in case of detecting and isolating misbehaving nodes.
