The LEACH protocol is a popular protocol used in underwater wireless sensor network analysis and simulation. This paperanalyses the effect of varying the parameter values used in the LEACH protocol.Simulation results are presented. We show that the parameters normally used apply to a specific network only. Researchers have focused on Underwater wireless sensor networks (UWSNs). Because there are a lot ofapplications we used. The UWSN consists of many small sensor nodes that contain a small andself-charged battery. Sometimes it is possible to change the power source of the node battery but sometimes it isimpossible to do so, and this varies depending on the nature of the network environment so, the underwater wireless sensornetwork may be destroyed over time.
