This paper develops and compares different sensor network architecture designs that can be used for monitoring underwater pipeline infrastructures. These architectures are underwater wired sensor networks, underwater acoustic wireless sensor networks, RF (radio frequency) wireless sensor networks, integrated wired/acoustic wireless sensor networks, and integrated wired/RF wireless sensor networ...

Underwater sensor networks (UWSN) resemble terrestrial sensor networks in many aspects. However, the high propagation delay and limited bandwidth make terrestrial sensor network’s protocols unsuitable for UWSN. Underwater sensor node are powered by batteries which are even difficult to recharge. So, energy efficiency is major concern for underwater routing. In this paper ,based on VBF, we provi...

Underwater sensor networks are emerging as a promising distributed data management system for various applications in underwater environments, despite their limited accessibility and restricted energy capacity. With the aid of recent developments in ubiquitous data computing, an increasing number of users are expected to overcome low accessibility by applying queries to underwater sensor networ...

Through adding the trusted protocol, trusted control and management mechanism on existing network architectures, a protocol architecture for trusted underwater acoustic sensor networks is presented, and the constitutes and functions of each part are described.

This study addresses the optimization of node redeployment coverage in underwater wireless sensor networks. Given that nodes could easily become invalid under a poor environment and the large scale of underwater wireless sensor networks, an underwater sensor network redeployment algorithm was developed based on wolf search. This study is to apply the wolf search algorithm combined with crowded ...

Underwater acoustic network is one of the rapidly growing areas of research and finds different applications for monitoring and collecting various data for environmental studies. The communication among dynamic nodes and high error probability in an acoustic medium forced to maximize energy consumption in Underwater Sensor Networks (USN) than in traditional sensor networks. Developing energy-ef...

One of the current trends of the wireless communication is the underwater communication .The two most fundamental problems in underwater sensor network are sensing coverage and network connectivity. The coverage problem reflects how well a sensor network is tracked or monitored by sensors. An underwater wireless sensor networks is the emerging field that is having the challenges in each field s...

Underwater sensor networks have received growing interests recently [7], [5], [4], [1]. Compared with traditional techniques used in underwater activities such as scientific exploration and commercial exploitation, underwater sensor networks empower people to monitor or detect phenomena more accurately and timely in extended areas. The medium access control (MAC) protocol is very important to t...
