“…In this scheme monitoring nodes are used to properly monitor the behaviors of the nodes in the network and nodes are encouraged for cooperation. Jedari et al 38 proposed So‐Watch (Social Watchdog) system that uses a reputation scheme that identifies the number of selfish nodes and the level of selfishness. Kou et al 39 proposed a strict reward and punishment model to tackled the issue of selfishness.…”

Many Internet of Things (IoT) applications have been developed and implemented on unreliable wireless networks like the delay tolerant network (DTN); however, efficient data transfer in DTN is still an important issue for the IoT applications. One of the application areas of DTN is vehicular delay tolerant network (VDTN) where the network faces communication disruption due to lack of end‐to‐end relay route. It is challenging as some of the nodes show selfish behavior to preserve their resources like memory and energy and become noncooperative. In this article, an honesty‐based democratic scheme (HBDS) is introduced where vehicles with higher honesty level are elected as heads—during the process. Vehicles involved in the process would maximize their rewards (reputation) through active participation in the network activities, whereas vehicles with noncooperative selfish behavior are punished. The honesty level of the heads is analyzed using Vickrey, Clarke, and Groves (VCG) model. The mathematical model and algorithms developed in the proposed HBDS technique are simulated using the VDTNSim framework to evaluate their efficiency. The performance results show that the proposed scheme dominates current schemes in terms of packet delivery probability, packet delivery delay, number of packets drop, and overhead ratio.

“…In Jedari et al, a reputation‐based scheme is proposed to handle selfish behavior by using watchdog nodes in opportunistic mobile networks. Specifically, a reputation system is designed, where the watchdog nodes update the reputation of other nodes based on the direct and indirect watchdog information for identifying selfish nodes in the network.…”

Delay/disruption tolerant networks (DTNs) are potentially applicable in the challenged scenarios like post-disaster environments. In such networks, data forwarding generally relies on the mutual cooperation of the nodes. However, in reality, despite the availability of necessary resources for data forwarding, a node could misbehave by dropping messages received from other nodes with whom it has no strong social ties. Such a node is called a socially selfish node, which would cause a poor delivery ratio in the network. In this paper, we aim to address the problem of multicast data forwarding in the presence of such selfish nodes, by means of efficient relay selection in DTNs. First, we define a realistic reputation model, in contrast to existing models, to define the socially selfish/misbehaving nodes in the network. Further, a game-theoretic analysis is carried out that implies data forwarding cost is also an influential parameter in handling selfishness/misbehavior. Subsequently, the problem is formulated as a constrained optimization problem, which is NP hard. Therefore, a heuristic is proposed by combining the reputation of a node and the cost of message forwarding to appropriately identify relay nodes, thus improve the performance of the multicast message delivery in the network. We utilize a social metric, centrality to minimize the message forwarding cost in terms of the number of relay nodes. Finally, the comparative performance evaluation in ONE simulator with practical scenarios shows the superiority of the proposed scheme over the other prominent schemes.

“…There are equal chances of nodes to leave the connected domain due to their dynamic behavior. The authority assignment for trust evaluation is also partially based on the model used for comparisons as given in Jedari et al (2019). As far as the utilization of network's node degree is concerned, the degree of nodes keeps on changing due to the continuously evolving pattern of the network.…”

“…Most of the network modeling and its analysis afterward is done over static networks (Jung et al, 2013, Thilakarathna et al, 2013, Thilakarathna et al, 2016, Zhou et al, 2018, which is unrealistic. Also, the degree of nodes in the network may reflect malicious behavior as stated in (Jedari et al, 2019;Rebecchi, 2014). Such a situation arises in social networks when some terminal node exhibits the property of structural holes in a network.…”

With the enormous use of internet of things-based devices for enabling smart agriculture, there is a significant need for efficient systems in order to improve agricultural practices. It can help efficiently to develop optimal web-based information system using the data of field monitoring. But, the collection of such data in the presence of connectivity disruptions poses new challenges for users. This paper targets to determine such offloaders with less infrastructural costs to enable smart agriculture based on network heuristics. Although, few works contribute to the trust established, most of them are applicable only for static networks. This paper explores a trust-based solution for mobile data offloading. This paper identifies the need and impact of trust determination using the trust model algorithm. The proposed algorithm outperforms the hybrid trust-based mobility aware clustering algorithm for trust-based offloaders with up to 13% better offloading potential saving a minimum of 8 pJ energy per user with just 25% contributors with 50% lesser time delay.
