摘要

提出了一种新的基于位置的ad-hoc组播路由协议。从众所周知的GPSR协议扩展到组播开始，通过对目标组进行聚类估计，并将每个集群视为单个节点进行数据包转发，从而减少了带宽消耗。由于新协议限制了分组复制的数量，提高了网络效率。在进行实时组播业务时，可以在不明显影响端到端延迟的情况下提高报文的下发率。我们通过仿真研究了我们的协议的性能，用模拟器实现了一个完整的MAC协议。这允许在带宽有限的情况下测量性能并验证结果

A Novel Location-Based Multicast Protocol for Ad-Hoc Networks

A novel location-based multicast routing protocol for ad-hoc networks is proposed. Starting from a well-known extension of the GPSR protocol to multicast, reduced bandwidth consumption is obtained by performing clustering estimation of the destination group and by considering each cluster as a single node for packet forwarding. As the new protocol limits the number of packet replications, network efficiency is improved. When real-time multicast traffic is carried, the packet delivery ratio is increased without noticeably affecting end-to-end delay. We study the performance of our protocol through simulation, with a simulator implementing a full MAC protocol. This allows to measure the performance in bandwidth-limited scenarios and to validate the results
