APPARATUS AND METHOD TO GURANTEE RELIABLE DATA TRANSMISSION FOR LOW-RATE WIRELESS PERSONAL AREA NETWORKS(LR-WPANS)

摘要

PURPOSE: a kind of LR- WPANs (Low-Rate wireless personal domain networks) of the reliability of method and apparatus guarantee data transmission are supplied to the data link layer IEEE 802. for the reliability for guaranteeing that data are transmitted15.4 LR-WPANs. ;CONSTITUTION: data transfer part transmits the data (130) transmitted from upper layer. It can not normally be conveyed when radio channel collision is generated with data, data transfer component re-executes data transmission. A kind of Control for Dependability component management and control data transmit confidence level. A kind of increase for preventing the node for obscuring control section transmission loss that can be created as interstitial content with network. A kind of transmission of reception notifier processes unit receives confirmation message and is sent to sending node to be received number in error and congestion data packet;The 2011 of copyright KIPO submissions
