- Abstract
In underwater wireless sensor networks (UWSNs), there are a number of sensor nodes that perform collaborative monitoring tasks over a defined area. The sensor nodes move into a compromised stage during network operations for various adverse reasons. These compromised nodes are unable to trust each other's capabilities to run a network, thus creating a hindrance in network operations. In the past, various trust models based on different parameters were designed to enhance trust among nodes, but these models ignored the existence of redundant data. In this paper, a trust-based security model for UWSNs is proposed to enhance the trust among the nodes in the network. The total trust of each cluster head (CH) is taken as a sum of its direct trust and its recommendation trust value, which are a combination of communication trust, data collection trust and energy trust. If the trust value of a CH is below a threshold value, the CH will be replaced by a CH with a higher trust value. This paper provides a comparative analysis of the proposed trust model with an existing technique, and discusses the effi-ciency of the proposed technique on the basis of increased trust and lower risk of attack among the nodes.
