A Hybrid Optical-Acoustic Modem Based on MimoOfdm for Reliable Data Transmission in Green Underwater Wireless Communication

Abstract

Green Underwater Wireless Communication (GUWC) are greatly finding its applications in seashore explorations, Internet of Underwater Things (IoUTs), Water Quality monitoring, Offshore data collection, Tactical surveillance, Assisted navigation, natural disaster alerts and preventions etc.  Therefore, the undersea activities are changed according to the development tactics and may offer new technology. this new technology directly in support of ongoing science and engineering programs during the subsequent years, there'll be exploring applications of. Many potential applications in a long range of environments from the deep sea to coastal waters was done by using the high-speed underwater optical-acoustic(hybrid) communication. Therefore, there is a need for both visual (optical) and acoustical communication together in a one modem called optical-acoustic modem towards the varying depths and variety of nature of ocean causes. a hybrid MIMO-OFDM based opto-acoustic modem for Green Underwater Wireless Communication (GUWC) was proposed in this paper, that increases the network performance, and affirms eminent rate/speed by choosing the allowable communication either optical or acoustical link.
