Cooperative time synchronization based on industrial wireless networks

According to spatial averaging and not traditional time averaging, cooperative time synchronization supposes a new method for time synchronization in wireless sensor networks. In this work, we present a cooperative time synchronization protocol that uses broadcasting and spatial averaging for the characters of industrial wireless networks. This protocol can dynamically adjust the received rate of the time synchronization messages on time and space, in order to achieve high precision and strong robust. Simulation estimates that the protocol has much better synchronization performance than traditional protocol only using time averaging in multiple-hop networks.
