Abstract

Abstract - The term MANET describes distributed, mobile, wireless, multihop networks that operate without the benefit of any existing infrastructure. When several nodes are participating in the Mobile Ad hoc Network collision of packets may happen and sending the time bounded packets to the destination node is difficult. Different nodes can use the same bandwidth simultaneously as long as they are sufficiently separated and do not interfere with each other. In this paper we are employing RealTime MAC(RT MAC) for data transmission between mobile terminals and support real time traffic, such as streamed voice or video, which has a more demanding quality-of-service (QoS) requirement and often requires bandwidth reservation. It uses a Bayesian algorithm to calculate contention probabilities and enable faster convergence of the reservation procedure. The Real Time MAC is free of the “hidden terminal” problem, and is designed such that reservations can be made quickly and efficiently with negligible probability of conflict. It is fully-distributed and parallel and a reservation is made through a localized conversation between nodes in a 2-hop neighborhood, and scalable.

基于实时MAC协议的移动自组网带宽预留

摘要:术语MANET描述了在没有任何现有基础设施的情况下运行的分布式、移动、无线、多跳网络。当多个节点同时参与移动自组网时，可能会发生报文冲突，难以将有时间限制的报文发送到目的节点。不同的节点可以同时使用相同的带宽，只要它们之间有足够的距离并且互不干扰。本文采用实时MAC(real time MAC, RT MAC)进行移动终端之间的数据传输，支持实时流量，如流语音或流视频，这些流量对服务质量(QoS)要求更高，通常需要预留带宽。它使用贝叶斯算法来计算争用概率，从而加快预订过程的收敛速度。Real Time MAC不存在“隐藏终端”问题，其设计使得可以快速有效地进行预订，而冲突的可能性可以忽略不计。它是完全分布式和并行的，并且通过2跳邻居中的节点之间的本地化对话进行预订，并且是可扩展的。
