Ocean exploration has received much attention lately and became very important research area since last one decade for pollution detection, target tracking, navigation and ocean monitoring for military surveillance purposes. For underwater communication network of sensors needs to be established to collect information. Underwater networks are different than territorial networks because of dynamic underwater environments and both have different sort of challenges. UWSNs have challenges like battery replacement, node localization, end to end delay, more data loss and high signal-to-noise ratio. Network topologies are considered dynamic in UWSNs because sensors are not stationary and moving with the water current. After deployment of sensor nodes, routing protocols plays vital role for secure and efficient communication. In UWSNs network lifetime and power consumption are considered major challenges in the way of underwater communication. Since last decade many protocols are presented to coupe up with these challenges efficiently in dynamic scenarios. In this chapter we have presented a protocol which predicts fast moving nodes and neighbor nodes to exclude them from clusters. In this way the skipped nodes became idle and conserve their energy. In next round of cluster formation residual energy level of idle nodes is found higher than used nodes so they will form cluster. Neighbor nodes cover overlapping area and used to collect a degree of matching information which later eliminated at aggregation level. Our proposed algorithm finds speed of moving nodes to differentiate the suitable and unsuitable nodes for the cluster. In addition we have also differentiated long range and short range communication for acoustic and optical mediums, which also helps to increase network life span. We have used advantages of both communication mediums for short range and long range communication where are they performed well.
