Exploiting Mobility to Improve Underwater Sensor Networks

Mobility has a dual role in underwater wireless sensor networks. On one hand, it might diminish the performance of networking protocols and impair network connectivity. On the other hand, it might improve data collection and boost networking-based services. In this paper, we discuss the potentials of exploring the controlled mobility of underwater sensor nodes to improve the performance of underwater sensor network applications. We highlight the advantages of the use of the mobility to boost the performance of several networking aspects of underwater sensor networks. Moreover, we discuss some of the challenges and we provide some guidelines when designing mobility-assisted networking protocols for underwater sensor networks. Finally, we point out some future research directions.
