Synchronization Protocol

The right measurement of network time delay is the basis of a good network service. With the research on the IEEE 1588 precision time synchronization protocol and MPLS (Multi-protocol Label Switching), a method to realize the network time delay measurement in the MPLS network is introduced. It is also pointed out that this method has very important significance for the rapid deployment of network and the network quality evaluation.

Internet of Things (IoT) is expected to change the everyday life of its users by enabling data exchanges among pervasive things through the Internet. Such a broad aim, however, puts prohibitive constraints on applications demanding time-synchronized operation for the chronological ordering of information or synchronous execution of some tasks, since in general the networks are formed by entities of widely varying resources. On one hand, the existing contemporary solutions for time synchronization, such as Network Time Protocol, do not easily tailor to resource-constrained devices, and on the other, the available solutions for constrained systems do not extend well to heterogeneous deployments. In this article, the time synchronization problems for IoT deployments for applications requiring a coherent notion of time are studied. Detailed derivations of the clock model and various clock relation models are provided. The clock synchronization methods are also presented for different models, and their expected performance are derived and illustrated. A survey of time synchronization protocols is provided to aid the IoT practitioners to select appropriate components for a deployment. The clock discipline algorithms are presented in a tutorial format, while the time synchronization methods are summarized as a survey. Therefore, this paper is a holistic overview of the available time synchronization methods for IoT deployments.

Synchronization Protocol

ZigBee technology is more and more used in complex and bad industrial monitoring and control environment. At the same time, ZigBee nodes are usually powered by batteries, so prolonging the working time and reducing the power consumption of the nodes is very important. If the wireless nodes can turn into sleep mode in spare time of communication, it will further reduce the node power consumption. But in sleep period, the node can't communication with other node, we need to synchronous awaken and dormancy, so precise time synchronization for wireless sensor network application is particularly important. This paper will apply FTSP algorithm in the ZigBee network and realize the network time synchronization. At the same time, it doesn't increase power consumption of the network.
