Low Latency Wireless Sensor and Actuator Networks : Analysis of LLDN and RT-WiFi

In this bachelor thesis, low latency wireless sensor and actuator networks are studied.In particular IEEE 802.15.4e/LLDN and IEEE 802.11g/RT-WiFi protocols. It is in-vestigated if the protocols are suitable for being used in typical industrial automationenvironments with high update frequencies of around 100 Hz. The protocols are exam-ined on a low level to shed lights on the sources of latency and followed by an analysis ofa specific configuration. It is found that LLDN is limited by low transmission rate andRT-WiFi is limited by interference with itself and other appliances. They both work wellfor update frequencies around 100 Hz.
