Sync MAC Protocol to Control Underwater Vehicle Based on Underwater Acoustic Communication

In this paper, we propose a sync-mechanism optimized for MAC protocol, which can be appropriate mechanism for controlling an underwater vehicle efficiently based on underwater acoustic communication. At present, underwater vehicle control system has difficulties and limits due to some underwater restrictions. For controlling the underwater vehicle, acoustic communication has many different features, unlike terrestrial wireless communication. The existing medium has limited wireless bandwidth, high transmission energy consumption and long propagation delay. And most of existing underwater MAC protocols haven't considered yet about nodes mobility, as well underwater vehicles. In this paper, we present our proposed sync-mechanism to reflect above-mentioned underwater features and we describe the methods to prevent data collision.
