论文摘要
文献中已经提出了许多用于地理播的方案。已经表明，由于路线寿命有限和频繁的网络碎片，显式路线设置方法的性能与货物销量相差不佳。基于广播的方法具有相当大的冗余，并大大增加了协议的开销。本文提出了一种完全分布和强大的地理播种方法，该方法对频繁的拓扑变化和网络碎片化具有弹性。一种基于距离的向后算法用于减少啤酒花的数量，并引入了一种新的机制来减少冗余广播。对各种方案进行了评估建议协议的性能，并与简单的洪水和基于显式路由设置的协议进行了比较。
Numerous protocols for geocast have been proposed in literature. It has been shown that explicit route setup approaches perform poorly with VANETs due to limited route lifetime and frequent network fragmentation. The broadcast based approaches have considerable redundancy and add significantly to the overhead of the protocol. A completely distributed and robust geocast approach is presented in this paper, that is resilient to frequent topology changes and network fragmentation. A distance-based backoff algorithm is used to reduce the number of hops and a novel mechanism to reduce redundant broadcasts is introduced. The performance of the proposed protocol is evaluated for various scenarios and compared with simple flooding and a protocol based on explicit route setup.
