Summary: VANETs enable vehicles to communicate with RSUs and other vehicles, contributing to improved traffic efficiency, accident safety, and entertainment services. However, intermittent connectivity poses limitations. To address this, ICV-DTNs, a subset of DTNs, have been proposed. Security is explored less compared to routing, with flood attacks causing low message delivery ratios and high message loss ratios. Previous algorithms lack efficiency in detection, lack demonstration of resource consumption, and lack a comprehensive definition of flood attacks. This article proposes a unique taxonomy, evaluates algorithms, and highlights open research areas for flooding attacks in ICV-DTNs.

Summary: This article discusses the issue of effective DTN data transmission for IoT applications based on unstable wireless networks. It focuses on the case of nodes that disrupt VDTN connections and investigates their impact on nine VDTN routing algorithms. The outcomes indicate that considering the form of inappropriate behavior, message duplication, and smart selection of next-hop can enhance the resistance of routing methods to node misconduct.

Summary: Multi-copy routing is a method that increases message delivery probability in the Vehicular Delay Tolerant Network (VDTN) by creating and forwarding copies to nodes. Generating too many copies can lead to potential congestion. To solve this problem, a feasible approach is to limit the number of copies generated. However, improper copy distribution can result in copies remaining in a small area and a high local density, which reduces overall performance. This paper proposes an effective Q-learning based VDTN multi-copy routing algorithm that controls the distribution of message copies and alleviates high local density.

Summary: Routing in Delay Tolerant Networks (DTNs) is challenging due to the lack of end-to-end paths and limited resources on each node. Existing forwarding schemes focus on maximizing delivery ratio and reducing delivery delay, but do not consider energy and buffer utilization when selecting relay nodes. To address this, we propose a new forwarding scheme that considers service level, buffer space, and energy level to select suitable relay nodes and achieve desired delivery ratio.

Summary: Mobile devices can store, communicate, and disseminate large data files across networks, but it is challenging in Delay Tolerant Networks due to lack of connectivity and short contacts among nodes. Existing protocols are not suitable for the data-intensive mobile era, so a large data routing protocol is proposed to chop data into chunks for forwarding, achieving a higher delivery rate compared to other routing strategies.
