Title:
SIGNAL TRANSMITTING/RECEIVING DEVICE AND METHOD IN MESH NETWORK
Document Type and Number:
WIPO Patent Application WO/2016/190707
Kind Code:
A1
Abstract:
The present invention relates to a technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and the Internet of things (IoT). The present invention can be used for intelligent services (smart home, smart building, smart city, smart car or connected car, health care, digital education, retailing, security and safety related services, and the like) based on the technology. The present invention provides a method by which a node transmits a signal in a mesh network, the method comprising the steps of: transmitting a packet; receiving at least one packet transmitted from at least one peripheral node except for the node, after transmitting the packet; determining whether the at least one peripheral node has normally received the packet on the basis of the at least one packet; and retransmitting the packet if it is determined that it is necessary to retransmit the packet, on the basis of the determination result.
