论文摘要
车辆临时网络（VANET）是移动无线网络的适当子集，该网络在节点上是夸张的，这些车辆在主板OBU（在机上）上装有特殊的电子设备，使他们能够转移并从Vanet中的其他车辆中接收消息。此外，车辆之间的通信，Vanet界面是通过与道路基础设施的联系点捐赠的。 Vanet是一组马力。与Manets节点不同，Vanet节点的移动非常快。在危险区域传播紧急消息和警报的永久途径是一项非常具有挑战性的任务。因此，路由在Vanets中起着显着的责任。减少网络开销，避免网络拥堵，增加交通拥堵和数据包的交付比率是与货物货车路线相关的最重要问题。此外，Vanet网络还会受到各种安全攻击。在基本vanet系统中，在确认发生间接延迟时，使用算法来进行攻击。本文提出（p-secure）方法，用于在确认时间之前检测DOS攻击。这减少了用于处理和提高货物安全性的开销延迟。仿真结果表明，就PDR，E2E_DELAY，吞吐量和下降数据包率而言，P-Secure方法比Obumodelvanet方法更有效。
Vehicular Ad-Hoc Networks (VANET) are a proper subset of mobile wireless networks, where nodes are revulsive, the vehicles are armed with special electronic devices on the motherboard OBU (On Board Unit) which enables them to trasmit and receive messages from other vehicles in the VANET. Furthermore the communication between the vehicles, the VANET interface is donated by the contact points with road infrastructure. VANET is a subgroup of MANETs. Unlike the MANETs nodes, VANET nodes are moving very fast. Impound a permanent route for the dissemination of emergency messages and alerts from a danger zone is a very challenging task. Therefore, routing plays a significant duty in VANETs. decreasing network overhead, avoiding network congestion, increasing traffic congestion and packet delivery ratio are the most important issues associated with routing in VANETs. In addition, VANET network is subject to various security attacks. In base VANET systems, an algorithm is used to dicover attacks at the time of confirmation in which overhead delay occurs. This paper proposes (P-Secure) approach which is used for the detection of DoS attacks before the confirmation time. This reduces the overhead delays for processing and increasing the security in VANETs. Simulation results show that the P-Secure approach, is more efficient than OBUmodelVaNET approach in terms of PDR, e2e_delay, throughput and drop packet rate.
