Sender-receiver Reference Broadcast Synchronization
Shi Kyu Bae · 2014
Time Synchronization Schemes for Wireless Sensor Networks have been classified into two categories in terms of message flow; namely, Sender-receiver and Receiver-receiver. While Sender-receiver type has been used traditionally, RBS (Reference Broadcast Synchronization), the representative of Receiver-receiver approach, was developed to provide higher synchronization accuracy by removing the sender's non-deterministic delay for the critical path, which approach has been referenced by so many other WSN synchronization schemes till now. However, RBS has limitations that it consumes too much energy to exchange large amount of messages and does not support an absolute global clock efficiently over an entire network. In this paper, we propose a new synchronization scheme to provide an absolute global clock for a network, which has RBS-like approach and less message exchange so as to reduce power consumption.
