A Low Overhead Time Slot Synchronization Mechanism for Wireless Ad Hoc Network
Yaowen Ye, Xin Huang, Dasheng Zhao · 2024
This paper addresses the issues of time synchronization and timeslot synchronization in Ad Hoc networks. It proposes a distributed, low-overhead, and highprecision synchronization algorithm that utilizes baseband hardware to address the time of received wireless frames, implements hop-by-hop distributed synchronization based on gradient diffusion. Compared to traditional algorithms, this approach significantly improves synchronization accuracy, achieving microsecond-level precision. The algorithm is distributed, with its communication overhead and computational complexity only dependent on the number of one-hop neighbor nodes. The overhead introduced by synchronization messages is on the order of 100 bps.
