摘要

在以信息为中心的网络(ICN)中,客户端在需要内容时会生成一个兴趣数据包。兴趣数据包携带内容名称并通过网络传播,直至到达适当的缓存内容存储区或内容生产者。如果兴趣数据包被正确地转发到可能的内容位置,则搜索内容的检索速度会更快。高效、优化的兴趣转发技术是任何 ICN 成功实施的关键要求。本文介绍了一种基于进化博弈论的以信息为中心的车载网络兴趣转发方法。它采用公共物品博弈(PGG)策略来转发兴趣数据包,以便尽早找到内容。兴趣数据包被建模为商品,各种参与实体被归类为合作者或叛逃者。博弈的目的是将货物(兴趣数据包)发送到合法的内容存储区。合作者试图以最佳方式交付兴趣包,因此他们会得到一定的奖励。然而,叛逃者则不会获得奖励,因为他们不参与游戏。游戏开始时,玩家选择一种策略,并一直坚持到游戏结束。在兴趣转发过程中,节点会选择积分较高的邻居作为下一级转发者。本文对该方案进行了数学分析,以确定本文提出的各种主张。通过在基于 ndnSIM-2.0 的 ns-3 中进行仿真,也验证了数学上确定的主张。该模型与其他四种现有的 ICN 转发方法进行了比较,仿真结果表明新算法的性能更好。

Evolutionary game based interest forwarding in information centric vehicular networks (R2)

In Information Centric Network (ICN) a client generates an interest packet when it is in need of a content. The interest packet carries the content name and propagates through the network till it reaches an appropriate cached content store or the producer of the content. Retrieval of the searched content is faster if the interest packet is forwarded in right direction towards a probable content location. An efficient and optimal interest forwarding technique is the key requirement for the success of any ICN implementation. This paper describes an interest forwarding approach for information centric vehicular networks based on evolutionary game theory. It uses the Public Goods Gaming (PGG) strategy to forward interest packets so that the content can be located at the earliest. The interest packets are modeled as goods and various participating entities are categorized either as cooperator or defector. The purpose of the game is to deliver the goods (the interest packet) to the rightful content store. Cooperator tries to optimally deliver the interest packets and hence they are rewarded with certain incentives. However, defectors are not rewarded as they do not participate in the game. At the beginning, a player selects a strategy and confined to it till the completion of the game. During interest forwarding, a node selects its neighbor(s) having higher credits as next level forwarder. The scheme is analyzed mathematically to establish various claims made in this paper. The mathematically established claims are also validated through simulation in ns-3 based ndnSIM-2.0. The model is compared with four other existing ICN forwarding approaches and simulation results depict that the new algorithm performs better.

期刊介绍: Vehicular communications is a growing area of communications between vehicles and including roadside communication infrastructure. Advances in wireless communications are making possible sharing of information through real time communications between vehicles and infrastructure. This has led to applications to increase safety of vehicles and communication between passengers and the Internet. Standardization efforts on vehicular communication are also underway to make vehicular transportation safer, greener and easier. The aim of the journal is to publish high quality peer–reviewed papers in the area of vehicular communications. The scope encompasses all types of communications involving vehicles, including vehicle–to–vehicle and vehicle–to–infrastructure. The scope includes (but not limited to) the following topics related to vehicular communications: Vehicle to vehicle and vehicle to infrastructure communications Channel modelling, modulating and coding Congestion Control and scalability issues Protocol design, testing and verification Routing in vehicular networks Security issues and countermeasures Deployment and field testing Reducing energy consumption and enhancing safety of vehicles Wireless in–car networks Data collection and dissemination methods Mobility and handover issues Safety and driver assistance applications UAV Underwater communications Autonomous cooperative driving Social networks Internet of vehicles Standardization of protocols.
