Abstract—Wireless technology has taken part of our daily life which paved the way to underwater wireless communication to flourish as a research area. This research field is important for exploration of the seabed as oceanographers stated that there are still unexplored ocean perceptions. Latency and distance are considered to be the main factors that confronts this particular field and degrades the overall performance. This paper investigates the performance of RF signals in varying water depths. A point to point system was first considered with 2 nodes, the results of this experiment along with our previous work aroused the idea of Star topology. Another experiment was done testing the proposed topology within a particular distance before the data is completely lost. Moreover, a relaying technique using amplify and forward, was introduced to the system at high depth where the data is lost; changing the topology from star to line topology. The system performance was measured in terms of end to end delay and calculating the throughput of the whole system.
