TRANSPORT METHOD TO SATISFY REQUIRED COMMUNICATION RELIABILITY IN WIRELESS SENSOR NETWORKS

摘要

PURPOSE: A transport method which meets required communication reliability in a wireless sensor networks is provided to reduce memory use of traffic of which communication reliability is low by storing and re-transferring recover data in a node determined according to the communication reliability of traffic. CONSTITUTION: A communication reliability value of a sensor network is set up, and a source node is initialized. Data are transferred to a destination node through the source node, and a cache node is set up based on the communication reliability value and an estimated packet transmission ratio value.
