Abstract
The IoT is transforming the ordinary physical objects around us into an ecosystem of information that will enrich our lives. The key to this ecosystem is the cooperation among the devices, where things look for other things to provide composite services for the benefit of human beings. However, cooperation among nodes can only arise when nodes trust the information received by any other peer in the system. Previous efforts on trust were concentrated on proposing models and algorithms to manage the level of trustworthiness. In this paper, we focus on modelling the interaction between trustor and trustee in the IoT and on proposing guidelines to efficiently design trust management models. Simulations show the impacts of the proposed guidelines on a simple trust model.
Highlights
We evaluate the performance of the proposed guidelines by analysing the binary trust game in the simulated Internet of Things (IoT) network
We first examine a scenario with a population composed of only cooperative nodes and no trust management model: the goal is to understand which is the payoff that can be achieved in an ideal network
We modelled the interactions among nodes in the IoT following a binary trust game to study how trust can arise between them
Summary
The Internet of Things (IoT) has become one of the most important realities of our century, able to connect billions of devices. This paradigm allows us to connect everyday objects seamlessly to the Internet, in any place and at any time [1]. Importance of Trust in the Internet of Things. Trust has been recognized as a critical factor for the Internet of Things. Trust management allows multiple objects to share opinions about the trustworthiness of other devices. Trust is the critical factor in almost every aspect of the IoT and in network applications.
