수중 음향 Ad-Hoc 네트워크를 위한 접속제어 프로토콜 설계

Abstract

The paper deals with a new approach to underwater acoustic based Ad-hoc communication, which allows major design strategies for Media Access Control (MAC) in underwater networks. The proposed MAC aims at deploying AUV-centric star topology, which minimizes overhead of sensor nodes and improves energy-efficiency. Furthermore, that is also well under long and unknown propagation delays of the underwater acoustic medium. The implemented MAC protocol makes it easier to achieve frame synchronization than TDMA due to deploying localized schedule time, in addition to saving energy consumption by letting nodes sleep. It is also superior to MACA and MACAW in terms of propagation delay. This scalable centralized protocol has the potential to serve as a primer for development of MAC protocol for future underwater acoustic based ad-hoc networks.
