有限协作无线网络中的广播延迟研究

On the Broadcast Latency in Finite Cooperative Wireless Networks

Anvar Tukmanov, Zhiguo Ding, Said Boussakta, Abbas Jamalipour

摘要:

本文的目的是研究合作对系统延迟的影响,量化为将广播消息传递给所有预期接收器所需的重传次数。与现有的广播方案,节点之间的距离没有明确考虑的作品,我们研究小尺度衰落和传播路径损耗的联合效应。此外,我们研究合作的应用有限的网络,即当合作节点的数量是小的。随机几何和顺序统计量被用来开发分析模型,紧密配合非合作的情况下的仿真结果,并提供了一个合作设置的延迟下限。我们证明,即使是一个简单的洪水的情况下,合作广播实现显着降低系统延迟。

英文摘要:

The aim of this paper is to study the effect of cooperation on system delay, quantified as the number of retransmissions required to deliver a broadcast message to all intended receivers. Unlike existing works on broadcast scenarios, where distance between nodes is not explicitly considered, we examine the joint effect of small scale fading and propagation path loss. Also, we study cooperation in application to finite networks, i.e. when the number of cooperating nodes is small. Stochastic geometry and order statistics are used to develop analytical models that tightly match the simulation results for non-cooperative scenario and provide a lower bound for delay in a cooperative setting. We demonstrate that even for a simple flooding scenario, cooperative broadcast achieves significantly lower system delay.
