摘要:

组播通信在移动自组网中起着至关重要的作用。移动自组网为军事战场场景、灾难和公共安全网络(PSN)中的多媒体数据通信提供了低成本、自配置的设备。对于相同容量的数据通信,与单播相比,多播通信在带宽消耗、电池功率和路由开销方面提高了网络性能。近年来,人们提出了许多组播路由协议(MRP),试图解决MRP中的问题和挑战。基于多播的组通信要求在节点移动性、竞争、路由和信道开销较大的情况下,动态构建高效可靠的多媒体数据通信路由。本文对目前已知的研究技术的优点和缺点进行了深入的分析,并提供了一个更好的环境,使可靠的MRP。它提出了一个充分的研究,各种服务质量(QoS)技术和现有的增强网格为基础的MRP。基于网状拓扑的多播路由协议根据其在路由机制上的增强和对按需多播路由协议(ODMRP)的QoS修改来改进性能指标而被分类。本文涵盖了最新的,强大的和可靠的QoS和网格基于MRP,根据其操作功能,其优点和局限性进行分类,并提供了它们的性能参数的比较。

英文摘要:

Multicast communication plays a crucial role in Mobile Adhoc Networks (MANETs). MANETs provide low cost, self configuring devices for multimedia data communication in military battlefield scenarios, disaster and public safety networks (PSN). Multicast communication improves the network performance in terms of bandwidth consumption, battery power and routing overhead as compared to unicast for same volume of data communication. In recent past, a number of multicast routing protocols (MRPs) have been proposed that tried to resolve issues and challenges in MRP. Multicast based group communication demands dynamic construction of efficient and reliable route for multimedia data communication during high node mobility, contention, routing and channel overhead. This paper gives an insight into the merits and demerits of the currently known research techniques and provides a better environment to make reliable MRP. It presents a ample study of various Quality of Service (QoS) techniques and existing enhancement in mesh based MRPs. Mesh topology based MRPs are classified according to their enhancement in routing mechanism and QoS modification on On-Demand Multicast Routing Protocol (ODMRP) protocol to improve performance metrics. This paper covers the most recent, robust and reliable QoS and Mesh based MRPs, classified based on their operational features, with their advantages and limitations, and provides comparison of their performance parameters.
