A new approach for trust management according to energy consumption in iot network nodes

Internet of things (IoT) is a concept that enables existences to feel and collect the required information from the physical world and share this collected information through the internet which can be used and progressed for different purposes. One of the main affairs facing these Internet of Things grids is the influence of malignant devices that can tentatively stop the provided services. These malignant nodes are the offensive that may run offensives to the other web gates by starting a harmonious attack. Confidence management plays an important role in IoT for increasing the users’ privacy and information security. In this paper, we shall new strategy for trust management is suggested to reduce energy consumption in IoT network nodes. The last, trust is calculated only for suspicious nodes instead of calculating for all kinds of network nodes. A threshold has been considered to determine suspicious nodes. The obtained results show that the proposed method has better performance than similar methods.
