With the recent advancement in the field of communication, computation and underwater wireless multimedia sensor network, researchers have gained a keen interest in a new challenge; fulfilling the quality of service (QoS) requirements both from the applications perspective, ranging from industrial monitoring to disaster prevention and from the networks perspective. However, providing full QoS support to any application is a critical problem since sensor nodes are highly resource constrained and have unreliable and highly dynamic wireless links. The diversities in the operational environment and communication channel have significant effect on the underwater network, so additional QoS support is required for underwater wireless sensor networks (UWSNs) than wireless sensor networks (WSNs). In this paper, we have explored QoS challenges and perspectives for WSNs and UWSNs.
