“…Many security approaches [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] employ the watchdog approach to unmask malicious nodes. However, although the use of the watchdog approach allows to detect malicious nodes, it has several limitations [4] and All security approaches using this technique inherit these limitations.…”

In this paper, we propose a new reputation approach, called I-WG (improved Watchdog). The aims is to eliminate selective dropping attack that occurs when malicious nodes drop packets at low rate to damage the network, while at the same time to avoid to be detected. The proposed approach is structured around four modules. The monitoring module overhears the forwarding activities of neighbors nodes using the promiscuous mode. The reputation module evaluates the nodes reputation values. We have have proposed a new reputation method that enable nodes to evaluate their neighbors in multiple monitoring sessions. Thus, the computed reputation value is used to determine the increment and decrement reputation rate. The exclusion module is responsible for excluding nodes with reputation values below the reputation threshold. The route selection module make restriction about discovered forwarding routes. Only forwarding routes satisfying the route incorporation threshold are accepted. The simulation results demonstrate that I-WG improves the success rate and reduces the number of packets dropped by malicious nodes, while increases the end-to-end delay.

“…Nodes are stimulated for taking part in the routing process. Sharma et al 40 proposed a reputation‐based scheme to detect selfish and malicious nodes and also stimulates such nodes for cooperation in delay tolerant networks. Cai et al 41 have presented an efficient incentive‐compatible routing protocol (ICRP) for DTNs.…”

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.
