The authors propose an informed search greedy approach that efficiently identifies the influencer nodes in the social Internet of Things with the ability to provide legitimate ***,the proposed approach minimizes the network size and eliminates undesirable *** that,the proposed approach ranks each of the nodes and prioritizes them to identify an authentic ***,the proposed approach discards the nodes having a rank(α)lesser than 0.5 to reduce the network complexity.αis the variable value represents the rank of each node that varies between 0 to *** with the higher value ofαgets the higher priority and vice *** threshold valueα=0.5 defined by the authors with respect to their network pruning requirements that can be vary with respect to other research ***,the algorithm in the proposed approach traverses the trimmed network to identify the authentic node to obtain the desired *** performance of the proposed method is evaluated in terms of time complexity and accuracy by executing the algorithm on both the original and pruned *** results show that the approach identifies authentic influencers on a resultant network in significantly less time than in the original ***,the accuracy of the proposed approach in identifying the influencer node is significantly higher than that of the original ***,the comparison of the proposed approach with the existing approaches demonstrates its efficiency in terms of time consumption and network traversal through the minimum number of hops.
