A Balanced Load Matching Rate Code Aware Routing Protocol based on network coding

As the foundation of network communication, routing protocols have become one of the critical technologies for the development of marine resources and marine military. However, due to the characteristics of underwater Ad hoc networks, such as long delay, narrow bandwidth and high bit error rate, the data transmission ability of traditional routing protocol is poor. In this paper, with the help of the idea of coding-aware routing, using network coding techniques, a coding-aware multipath routing protocol BMCAR(Balanced Load Matching Rate Aware Routing) with a balanced load matching rate based on network coding suitable for underwater environments is designed, and the BMCAR routing protocol actively explores and utilizes potential coding opportunities in the network during route discovery. A new routing metric BMCRM(Balanced Load Matching Rate-Coding Aware Routing Metric)is designed as the routing criterion. BMCAR Routing Protocol makes the coding opportunity more accurate and further increases the throughput of the network. It makes the transmission more reliable and more practical.
