论文摘要
制造过程的数字化导致了高度增加的连接设备。在此开发过程中，开发和实施了一个过程，该过程通过使用上下文信息来优化与干扰情况有关的IEEE 802.11系统。这是通过分为两个领域实现的。首先，数据提供商计算自己的干扰状况，以确定确定数据的最佳频率。在这种情况下，最佳意味着所选通道应具有最低的干扰能力。在第二步中，这些提供商还计算有关所有服务集标识符（SSID）的干扰信息。然后将测量数据分为允许的无线电通道。之后，收集的信息将转移到中心空间。已经存在的基础架构被用作进一步过程的初始点。提供商转移了新数据后，经纪人可以通知连接的用户推理情况有一个更新。通过这种开发的体系结构，一种方法可以面对隐藏的节点问题。实施了用于安全至关重要信息的系统。
The digitalization of manufacturing processes is leading to a highly increased amount of connected devices. In the course of this development a process was developed and implemented, which optimizes IEEE 802.11-systems relating to the interference situation by using context-information. This was realized by division into two fields. First of all, data providers calculate their own interference situation to determine the optimal frequency out of the ascertained data. In this case optimal means that the chosen channel should have the lowest interference power. In a second step these providers also calculating the interference information about all Service Set Identifier (SSID) in range. The measured data is then divided into the allowed radio channel. Afterwards the gathered information will be transferred to a central space. An already existing infrastructure is used as a initial point for the further process. As soon as the provider has transferred new data, a broker can inform connected users that there is an update in the inference situation. With this developed architecture an approach to face the hidden node problem is given. Additional a system for safety-critical information is implemented.
