近年来，物联网的概念越来越强大，设定了将数十亿设备集成到互联网的目标。因此，从这个角度来看，分配给低功率无线传感器网络的兴趣比以往任何时候都要高。本文从物联网概念的角度分析了SIGFOX的可扩展性。在科学研究中，有一系列的论文研究了SIGFOX问题，往往是在比较研究的水平上，而没有对通信协议的性能水平进行评估。本文旨在通过创建一个现实的SIGFOX通信模型来填补这一空白。此外，使用SDRS实现了一个已开发和测试的SIGFOX流量生成器。这使得评估大规模高密度类型的WSN网络的性能水平成为可能。这两种工具都代表了本文的创新之处。结果表明，为了在可用信道数为360的情况下获得较高的性能，在所提出的场景下，可以同时传输数据的传感器的最大数目约为100个。如果我们增加传感器的数量，雪崩效应就会随之而来，从而触发SIGFOX网络性能的急剧下降。最后提出了一系列解决方案，主要目的是提高大规模、高密度SIGFOX网络的性能水平。
In recent years, the IoT concept is more and more powerful, having set the goal of integrating billions of devices to the Internet. Thus, from this perspective, the interest allocated to low-power wireless networks of sensors is higher than ever. In this paper, the SigFox scalability is analyzed from the IoT concept point of view. In the scientific research, there are a series of papers which tackle the SigFox issues, oftentimes at a comparative study level, without evaluating the performance level of the communication protocol. This paper comes to fill this gap by creating a realistic SigFox communication model. Moreover, a developed and tested generator of SigFox traffic has been implemented, using SDRs. This allows the possibility of evaluating the performance level of WSN networks, of a large-scale high-density-type. Both of the suggested instruments represent the novelty of this paper. The obtained results show that the maximum number of sensors that can transmit data at the same time, using the proposed scenarios, is of approximately 100, in order to obtain a high level of performance when the number of available channels is 360. If we are to increase the number of sensors, an avalanche effect ensues which triggers the sharp decrease of the performance of the SigFox network. At the end of this work, a series of solutions are being suggested with the main purpose of increasing the performance level of large-scale, high-density SigFox networks.
