MAC protocol for measurement signal broadcasting in distributed ocean current estimation using underwater acoustic sensor networks

Abstract

This paper presents a media access control (MAC) protocol for distributed ocean current estimation using the underwater acoustic sensor network (UWASN). We present a spatial reuse time-division multiple access (TDMA) protocol. Based on measurement signal broadcasting process, we formulate the slot scheduling problem with a specific objective as an optimization problem that we resolve with a heuristic algorithm. We use computer simulations to analyze the proposed TDMA protocol's performance.
