METHOD OF TRANSMITTING PACKET IN LOW POWER WIRELESS PERSONAL AREA NETWORK AND LOW POWER WIRELESS PERSONAL AREA NETWORK PERFORMING THE SAME

摘要

A method of transmitting a packet in a low-power wireless personal area network (LoWPAN) comprises transmitting a fragmented packet to an intermediate node from a sender node, storing the fragmented packet in the intermediate node for retransmitting the fragmented packet to a receiver node when an error occurs in the fragmented packet or the fragmented packet is lost while the fragmented packet is transmitted to the receiver node, and transmitting the stored fragmented packet to the receiver node. The packet transmission method and a packet transmission system may reduce power consumption and traffic in a LoWPAN and enhance the reliability of the packet transmission.
