基于EBGR算法的车载Ad Hoc网络高效分组转发方法
Efficient Packet Forwarding Approach in Vehicular Ad Hoc Networks Using EBGR Algorithm
摘要：
车载自组织网络（VANcular Ad hoc Networks，VANcular Ad hoc Networks）是一种高度移动的无线自组织网络，在公共安全通信和商业应用中将发挥重要作用。由于快速变化的拓扑结构和车辆的高速移动性，在VAN中的数据路由是一项具有挑战性的任务。传统的移动自组织网络路由协议无法完全解决车载网络的独特性。在本文中，我们提出了EBGR（边缘节点基于贪婪路由），一个可靠的贪婪的位置为基础的路由方法，转发数据包的源/转发节点的传输范围的边缘中存在的节点作为最合适的下一跳，考虑节点移动的方向的目的地。我们提出了复兴移动模型（RMM）来评估我们的路由技术的性能。本文详细介绍了我们的方法和仿真结果表明，数据包的交付率显着提高相比，其他路由技术的VANET。
英文摘要：
VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Conventional routing protocols in MANETs (Mobile Ad hoc Networks) are unable to fully address the unique characteristics in vehicular networks. In this paper, we propose EBGR (Edge Node Based Greedy Routing), a reliable greedy position based routing approach to forward packets to the node present in the edge of the transmission range of source/forwarding node as most suitable next hop, with consideration of nodes moving in the direction of the destination. We propose Revival Mobility model (RMM) to evaluate the performance of our routing technique. This paper presents a detailed description of our approach and simulation results show that packet delivery ratio is improved considerably compared to other routing techniques of VANET.
