APPARATUS AND METHOD FOR ADJUSTING TCP(TRANSMISSION CONTROL PROTOCOL) SEGMENT IN WIRELESS SENSOR NETWORK BASED ON 6LOWPAN(IPV6 OVER LOWPOWER WIRELESS PERSONAL AREA NETWORK)

摘要

A kind of technology is disclosed, the fan marker wireless personal domain network (6LoWPAN) in wireless sensor network of the size (TCP) of TCP segments to improve TCP transmission performance based on an IPv6 more than low-power can be dynamically adjusted for the equipment. According to the present invention, it includes: gear ratio calculation unit that the device, which is used to adjust in TCP segment wireless sensor network based on 6LoWPAN, whether succeed based on whether grouping transmission ratio transmits the grouping and be sent to border router from present node for calculating, and calculates that average packet transmission ratio is based on grouping transmission ratio and prior packet transmission ratio carries out pre-stored data library; Link-quality determination unit determines that it includes average ratios that information is based in the one section of present node and border router of link-quality; Definitive result is based on relative to link-quality with a TCP segment adjustment average ratios, and adjusts the TCP segment of maximum segment length (MSS) in response to adjusted average packet transmission ratio. ;The 2016 of copyright KIPO submissions
