Adaptive Routing in Underwater Delay Tolerant Sensor Networks
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.
