Reconfiguration time and complexity minimized trust-based clustering scheme for MANETs

Abstract: A trust management mechanism for mobile ad hoc networks (MANETs) is proposed to cope with security issues that MANETs face due to time constraints as well as resource constraints in bandwidth, computational power, battery life, and unique wireless characteristics. The trust-based reputation scheme GlobalTrust is a reliable trust management mechanism. In this paper, a clustering algorithm is applied to the GlobalTrust scheme (named Cluster-based GlobalTrust (CGTrust)) to find the optimal group size to minimize … Show more

“…Trust management is a scheme that can enhance the security level by determining the reliability of an entity (based on its behavior pattern) in a network [5], or help improve networking functions, such as secure routing [6] and clustering [7]. The basic trust evaluation is based on peer-to-peer evaluations among nodes, where a honest node should behave in a way that is consistent with the majority of honest nodes in the network.…”

“…where K denotes the given number of shards in the blockchain system, G i and T G i represent the ith shard set and the aggregated trust of the corresponding shard, respectively. In (7), t j denotes trust value of node j in set G i , where G i stores the index of the node to be assigned in the ith shard group. Finding the optimal shard set (…”

“…GlobalTrust [11], [12] was used to calculate the trust level of the worker nodes, where all worker nodes report a local trust opinion (LTO) to the cluster head (CH) for trust evaluation. The reported behavior is observed based on the big data processing time for a certain period.…”

“…The computational complexity inside the cluster is derived as follows. The trust scheme used in this paper creates a trust quorum to judge the trust levels [11], [12]. When all clusters simultaneously compute trust values, the computational complexity of the cluster with the largest number of worker nodes will be O( N/k 2 ).…”

“…In order to provide data accuracy and security for the network, trust theory [9][10][11][12][13][14][15][16] has been gradually studied by researchers. Through the evaluation and storing the trust values of sensor nodes in WSNs, it can compute how much data from those nodes can be trusted when they are doing a certain job such as packet delivery and routing response.…”
