Effective MIMO-based Relay Selection for Quality of Service Management in Underwater Cooperative Wireless Sensor Networks

There has been a lot of interest in collaborative communications-based wireless relay networks as a highly effective approach to boost the transmission and endurance capacities of wireless networks. This has received a lot of attention from a variety of different people. On the other hand, there hasn't been a lot of research done or knowledge gained on how to choose. This is especially true in tough underwater wireless settings that have tight power supply limits. In this study, we offer an energy-efficient relay selection technique that ensures each link's quality of service (QoS) while addressing the aforementioned issues in MIMO-based UWA cooperative wireless sensor networks. To represent the UAW channel, we employ the Finite-state Markov chain. Additionally, we additionally take into account left-over relay energy, MIMO multiplexing-gain, diversity-gain, and other strategies in the relay selection procedure. By using the linear programming (LP) method, we put our suggested best relay selection methodology into practise. We do simulations to verify and assess our suggested system and demonstrate its superiority to other current schemes.
