Abstract

Recently, development of original technologies and connection technologies of UW-ASN for data transmission in underwater environment has been accelerated. Since propagation delay is inevitable at acoustic communication in underwater environment, the transmission time tends to be increased as network radius increases. Besides, there are difficulties of Multiple Access Control (MAC) service, which supports to avoid the collision and maintain reliable transmission condition. In this paper, a new scheduling method was proposed to eliminate the effect of interferences in a channel by taking both Gain-time and Guard-time into consideration.
