嗅探多跳多信道无线传感器网络

Sniffing Multi-hop Multi-channel Wireless Sensor Networks

Jelena Kovač, Jovan Crnogorac, Enis Kočan, Malisa Vucinic

摘要:

随着无线传感器网络的规模越来越大、复杂程度越来越高、作用越来越重要,有必要对网络流量进行深入分析。为此,嗅探器发挥着不可替代的作用。由于嗅探器是一种范围有限的设备,为了覆盖多跳网络,有必要考虑部署多个嗅探器。这激发了对网络中嗅探器的最佳数量和位置的研究。我们提出了一个解决方案的基础上,从图论的最小优势集。我们评估所提出的解决方案,并实现它作为一个扩展的6TiSCH模拟器。我们的解决方案假设一个50节点的场景,部署在2x2公里的室外区域,10%的数据包丢弃在所有通道,当使用10个嗅探器。

英文摘要:

As wireless sensor networks grow larger, more complex and their role more significant, it becomes necessary to have an insight into the network traffic. For this purpose, sniffers play an irreplaceable role. Since a sniffer is a device of limited range, to cover a multi-hop network it is necessary to consider the deployment of multiple sniffers. This motivates the research on the optimal number and position of sniffers in the network. We present a solution based on a minimal dominant set from graph theory. We evaluate the proposed solution and implement it as an extension of the 6TiSCH simulator. Our solution assumes a 50-nodes scenario, deployed in 2x2 km outdoor area, with 10% of packet drops over all channels, when 10 sniffers are used.
