WLAN Mesh Networks (WMNs) are a promising network architecture for IoT applications due to their self-healing and robust network formation capabilities. The IEEE 802.11s amendment standard integrates mesh functionality into the WLAN MAC layer, ensuring seamless peering and routing. Initially designed for testing, the Linux implementation of IEEE 802.11s includes basic peer link blocking mechanisms. Based on this, we present a new MAC address filtering approach for reliable topology control in WLAN mesh networks. Our modifications to the Linux kernel enable persistent link blocking and bidirectional link teardown, preventing the sporadic establishment of unwanted connections. Real-world experiments demonstrate the effectiveness of our approach.

We present BurstLR, a novel online resynchronization method for wireless burst transmitted sensor signals. Instead of clock alignment, our method uses approximative timestamp realignment by estimating the relation between sensor clock and receiver clock at the receiver. Only the sensor and arrival timestamps of samples are required. Thus, no additional communication as well as hardware is needed. In our experiments with two wireless sensor nodes (Nicla Sense ME), we achieved a reduction of the average quadratic distance with dynamic time warping between resynchronized acceleration signals that recorded the same arbitrary human motion trajectory by 54.95 % to 76.91 % compared to signals that used the arrival times for synchronization.
