大型传感器网络中基于网络编码的近优广播

Near Optimal Broadcast with Network Coding in Large Sensor Networks

Cédric Adjih, Song Yean Cho, Philippe Jacquet

摘要:

我们研究无线传感器网络的有效广播,网络编码。我们解决这个问题的同构传感器网络在飞机上。我们的结果是基于一个简单的原则(IREN/IRON),它设置相同的速率对大多数节点(无线链路)的网络。有了这个速率选择,我们给出了一个值的源的最大可实现的广播速率:我们的中心结果是证明了这种网络的最小割的值,被视为超图。我们的效率指标是从源发送一个数据包到每个目的地所需的传输次数:我们表明,IREN/IRON实现大型网络的近最优性,也就是说,渐近,几乎每一个传输带来新的信息从源到接收器。因此,网络编码渐近优于任何不使用网络编码的方案。

英文摘要:

We study efficient broadcasting for wireless sensor networks, with network coding. We address this issue for homogeneous sensor networks in the plane. Our results are based on a simple principle (IREN/IRON), which sets the same rate on most of the nodes (wireless links) of the network. With this rate selection, we give a value of the maximum achievable broadcast rate of the source: our central result is a proof of the value of the min-cut for such networks, viewed as hypergraphs. Our metric for efficiency is the number of transmissions necessary to transmit one packet from the source to every destination: we show that IREN/IRON achieves near optimality for large networks; that is, asymptotically, nearly every transmission brings new information from the source to the receiver. As a consequence, network coding asymptotically outperforms any scheme that does not use network coding.
