Underwater Sensor Network (UWSN) has attracted significant attention from both academia and industry. Different from terrestrial sensor nodes, underwater sensor nodes are usually mobile, much bigger, more energy-consuming, harder to recharge and suffer from more severe environmental conditions. Thus, an UWSN can be easily partitioned and no persistent routes from a source to a destination are available. Therefore, an UWSN can be viewed as a Delay/Disruption Tolerant Network (DTN). Moreover, an UWSN is always supposed to work for a long time to accomplish multiple tasks with various application requirements, such as delay and delivery ratio.
