Abstract

Vehicle Adhoc Network (VANET) permits self-organized infrastructure. Link or Connectivity breakage or long delay (intermittent connection) is an important issue in the VANET which arises due to the dynamic topological changes. Mainly two algorithms Vehicle assisted Data Delivery (VADD) and Opportunistic routing algorithm supports for handling delay/disruption tolerant network (DTN). Intention of DTN is to create dynamic link between the sender and receiver vehicle in the case of link disruption or absence of path between two nodes and forwards the data using store carry and forward. VADD carry and forward the data as much as possible in disconnected network using intersection mode, straightway mode or destination mode. Opportunistic routing can deal the unreliable data and intermittent connectivity in VANET by considering the multiple nodes as a next hop forwarder instead of considering pre-selected single node to be the best forwarder. This paper gives the study about various opportunistic routing algorithms for handling delay/disruption tolerant network.

车载ADHOC网络中各种DTN路由算法综述

车辆自组织网络(VANET)允许自组织基础设施。由于拓扑结构的动态变化，链路或连接中断或长时间延迟(间歇连接)是VANET中的一个重要问题。主要有两种算法支持车辆辅助数据传输(VADD)和机会路由算法来处理延迟/中断容忍网络(DTN)。DTN的目的是在两个节点之间的链路中断或缺少路径的情况下，在发送方和接收方车辆之间创建动态链路，并使用存储携带和转发方式转发数据。VADD通过交叉模式、直线模式或目的地模式在断开的网络中尽可能地进行数据的传输和转发。机会路由可以通过考虑多个节点作为下一跳转发器而不是考虑预先选择的单个节点作为最佳转发器来解决VANET中数据不可靠和间歇性连接的问题。本文研究了处理延迟/中断容忍网络的各种机会路由算法。
