A Novel Synchronization Algorithm for IEEE802.11 TDMA Ad Hoc Network
Zheng Wen, Ung Heo, Jaeho Choi · 2007
Time synchronization problem has been thoroughly studied for years, as it is a critical service for many applications. A novel self- synchronization algorithm is proposed for IEEE802.11 interface in TDMA-based ad hoc network, in which the advantage of RBS is exploited for the leading node election. Here, it overcomes shortcomings of previous methods by adopting a novel and efficient clock updating algorithm. The proposed scheme can be successfully applied to support real time applications such as voice calls over the multi-hop ad hoc network. The preliminary analytical results yields that the maximum clock offset is within 10 mus.
