A wireless sensor network (WSN) has the sensor nodes with gathered data packets from the environment and communicate with each other using wireless transceivers. It gathers the data using sensor nodes and conveys the information to the sink node. The critical issue in Under Water Sensor Networks (UWSN) is energy consumption. By decreasing the transmission collision and idle listening, the energy can be well-maintained. Multiple Rendezvous Multichannel MAC (MM-MAC) and Dynamic Duty Cycled Multiple Rendezvous Multichannel MAC (DMM- MAC) are used to transfer the data packet even in bursty traffic in UWSN. The concept of dynamic duty cycling is playing the vital role in achieving good results. In this paper, both intra and inter communication is established. Here, the cluster Head based data communication is taken where, they deal with the energy. These Cluster head is dynamically changed based on their energy level. Finally, the results of DMM-MAC with and without clustering are compared. From the simulation results it is well understand that DMM with clustering mechanism provides the improvement in the parameters like reduce in delay, improved rate in throughput and packet delivery and overhead for packet transmission is also greatly.
