Underwater acoustic sensor networks (UWASNs) are performing a lot of interest in ocean applications, such as ocean animal surveillance, ocean pollution monitoring, oceanographic data collection, assisted navigation, and offshore exploration, UWASN is composed of underwater sensors that engage sound to transmit data collected in this ocean. This cause to utilize sound is that radio frequency (RF) signals used by terrestrial sensor networks (TWSNs) can only transmit a few meters in this water. Unfortunately, this efficiency of UWASNs is deficient to that of this terrestrial sensor networks (TWSNs). This challenges in under water communication are propagation delay, high bit error rate and fixed bandwidth. Network coding is a hopeful technology that many researchers have encouraged due to its potentially significant benefits to increase this efficiency of data transmission. In this thesis, we use simulations to firstly evaluate this performance of different network topologies without network coding. Then increase this network throughput by using network coding technique. It also has a potential to decrease this end to end delay and improve this reliability. However, there are tradeoff (between delay and reliability) when network coding is used, and some limitations which we summarize.
