SYSTEM, METHOD AND NODE FOR TIME SYNCHRONIZATION USING RPL PROTOCOL

摘要

The present disclosure discloses system, method and node for time synchronization using RPL protocol. In contrast to the prior-art techniques, the present disclosure by system, method and node for time synchronization without incurring additional messaging overhead and achieve synchronization efficiency at par with existing techniques by reusing LLNs routing protocol primitives. The RPL is utilized to handle time synchronization as part of network formation which is referred to as Time Synchronization protocol using RPL for adhoc wireless sensor network (TSRPL) in this document. In order to sync time with every wireless sensor node, a non- loop hierarchical structure is required to propagate time synchronization across network, this requirement is satisfied as the RPL serves purpose to build a multi-hop tree like (DAG) network among sensor nodes, and timing handshake is performed using DAO- DAO/ACK by piggy backing time handshake information of sender-receiver approach of timing synchronization.
