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...
Flooding time synchronization protocol (FTSP) is an extendable, robust and steady protocol, which has high synchronization precision in wireless sensor networks. This paper improves the traditional FTSP, according to the characteristics of industrial wireless sensor networks. The key idea is that the node should avoid transmitting the time synchronization message with the rootID and seqNum, which...
A high performance communication library independent of hardware called HPCL/Ethernet is implemented based on commodity Ethernet NICs on the Linux. HPCL/Ethernet supports commodity Ethernet NICs by using the network device interface on the Linux kernel. Reliable message delivery is guaranteed in the software layer. Channel is adopted for simplifying buffer management and fixed-buffer policy is adopted...
