WIRELESS NETWORK CAPABLE OF USING A NETWORK CODING AND A METHOD OF ADAPTIVELY CONTROLLING A BUFFERING TIME IN THE WIRELESS NETWORK

摘要

PURPOSE: A wireless network and a method of adaptively controlling a buffering time are provided to provide followings: a technology reducing a coding failure rate by adaptively controlling a buffering time in an intersection node performing a network coding, especially RLNC(Random Linear Network Coding); a technology making the nodes in a wireless network to easily share the information through an alerting message and a cancellation message; and a technology suppressing a loop generation of the intersection nodes.;CONSTITUTION: A communication method of a specific intersection node in a wireless network including a plurality of intersection node performing a network coding in cross points comprises followings: a step obtaining information related to a number of hops from a source node to a specific intersection node or a number of hops from a specific intersection note to a destination node; a step adaptively controlling a buffering time in a specific intersection node by using the information; a step buffering a packet received from a specific intersection node by considering the controlled buffering time; and a step performing a network coding of a buffered packet and other packets.;COPYRIGHT KIPO 2013;[Reference numerals] (AA,BB) 1 + 2 transmission
