Wireless channel quality based packet scheduling mechanism for wireless networks

摘要

In wireless networks, channel quality depend on location of a mobile host. Performance of bandwidth utilization also depend on channel quality. If channel quality has gone bad, basestation useless transmit to wireless host that can not receive packets. As a result, total wireless network performance is degread. In this paper, we propose packet scheduling mechanism using signal to noise ratio (SNR) that an sign of wireless channel quality. We also examine the relation between channel quality and traffic performance. We substantiate total throughput improved over 20% by exclude useless traffic at base station in wireless networks.
