“…Since Panagakis et al [44] first presented their study on the performance degradation caused by selfish behavior in DTNs, researchers have shown signif-icant interest in this field. To evaluate the impact of selfish behavior on the performance of existing routing protocols, some works utilize theoretical analysis models, such as Continuous Time Markov Chains (CTMC), whereas others utilize simulations.…”

“…Moreover, in the literature investigating the impact of selfish behavior on routing performance [44,21], the authors generally consider the following two types of selfish actions: non-forwarding of messages and dropping of messages. Non-forwarding of messages means that a node refuses to relay messages for the nodes towards which it is selfish.…”

Message routing in mobile delay tolerant networks inherently relies on the cooperation between nodes. In most existing routing protocols, the participation of nodes in the routing process is taken as granted. However, in reality, nodes can be unwilling to participate. We first show in this paper the impact of the unwillingness of nodes to participate in existing routing protocols through a set of experiments. Results show that in the presence of even a small proportion of nodes that do not forward messages, performance is heavily degraded. We then analyze two major reasons of the unwillingness of nodes to participate, i.e., their rational behavior (also called selfishness) and their wariness of disclosing private mobility information.Our main contribution in this paper is to survey the existing related research works that overcome these two issues. We provide a classification of the existing approaches for protocols that deal with selfish behavior. We then conduct experiments to compare the performance of these strategies for preventing different types of selfish behavior. For protocols that preserve the privacy of users, we classify the existing approaches and provide an analytical comparison of their security guarantees.

“…By default, most of the protocols assume full node cooperation and little attention has been devoted to study the effect of reduced levels of cooperation. In fact, by applying and fine-tuning simple knowledgebased cooperation mechanisms, the routing performance can be considerably improved [78].…”

Abstract-This paper provides an introductory overview of Vehicular Delay-Tolerant Networks. First, an introduction to Delay-Tolerant Networks and Vehicular Delay-Tolerant Networks is given. Delay-Tolerant schemes and protocols can help in situations where network connectivity is sparse or with large variations in density, or even when there is no end-to-end connectivity by providing a communications solution for non realtime applications. Some special issues like routing are addressed in the paper and an introductory description of applications and the most important projects is given. Finally, some research challenges are discussed and conclusions are detailed.

“…In [19] and [20], studies of the effects of cooperation in DTNs are presented. The authors in both studies considered three routing protocols and studied the performance of these routing protocols in a non-cooperative environment, in terms of delivery delay and transmission overhead [20] and in terms of message delivery performance [19].…”

Delay Tolerant Networks (DTNs) is a promising current research field that have captured a lot of attention. In DTN, an end-to-end path is not assured and packets are transmitted from a source node to a destination node by the use of store-carry-forward based routing. In case of DTN, a source node or an intermediary node accumulates the packets in its buffer and holds them at the time of moving around in the network. In the majority of routing protocols, each node is necessary to truthfully pass on information. On the other hand, in certain scenarios few nodes possibly will break this principle, and pass on information in a greedy manner with the intention of maximizing their individual gain. The majority of the current security mechanism doesn"t depend on the practice of swarm intelligence based process for selection of untrusted nodes and recognizes the behaviour of illegal nodes. With the aim of solving this complication, this work employs the practice of swarm intelligence method, an Artificial Bee Colony (ABC) based greedy behaviour, in order to match the messages where a smart Mobile Trusted Module (MTM) is launched to supervise the forwarding progression of messages buffered in the node for the purpose of preventing the greedy behaviour. The performance of the proposed protocol was assessed in terms of average relay time, average message delivery ratio and reward ratio. Results confirm that the proposed protocol can onsiderably enhance the average message delivery ratio, diminished delay time and condensed packet overhead ratio by properly selecting the threshold values of forwarding counter and threshold hop counter.
