We make use of the existence of cell-disjoint paths in the 3D grid topology to design a new highly reliable adaptive geographic routing protocol called Grid-based Adaptive Routing Protocol (GARP) for Underwater Wireless Sensor Networks. In GARP, the underwater environment is viewed as a virtual 3D grid of cells. A packet is forwarded following a pre-constructed routing path from a node in a gri...

This chapter discusses the development of a short range acoustic communication channel model and its properties for the design and evaluation of MAC (Medium Access Control) and routing protocols, to support network enabled Autonomous Underwater Vehicles (AUV). The growth of underwater operations has required data communication between various heterogeneous underwater and surface based communica...

This paper presents a low-cost and low-power consumption asynchronous Wake-Up (WU) development to Underwater Wireless Sensor Networks (UWSN). An asynchronous WU offers important advantages for energyaware network polices, however it needs some specific hardware, an optimal configuration of system facilities and the interconnection with a core control unit. This proposed WU implementation has be...

Unlike a terrestrial wireless communication which uses radio waves, underwater communication relies on acoustic waves. The long latency and limited bandwidth pose great challenges in Underwater Media Access Control (MAC) design. So this paper proposes a new MAC protocol for wireless sensor acoustic network which are adaptable to underwater environment. This new protocol is based on the classic ...

In this paper, we tackle the malicious attacks in Underwater Sensor Networks (UWSNs). Underwater Sensor Networks (UWSNs) consists of variable number of sensors and vehicles that are deployed to perform collaborative monitoring tasks over a given area. In this paper, we use a novel routing protocol, called vector-based forwarding (VBF) protocol, to provide robust, scalable and energy efficient r...

During the underwater sensor networks (UWSNs) operation, node drift with water environment causes network topology changes. Periodic node location examination and adjustment are needed to maintain good network monitoring quality as long as possible. In this paper, a node redeployment algorithm based on stratified connected tree for UWSNs is proposed. At every network adjustment moment, self-exa...

The act of accessing the exact location, or position, a node in network is known as localization network. In this methodology, precise location each within can be made terms certain chosen nodes subset. This subset locating set and its minimum cardinality called number generalized hexagonal cellular novel structure for planning analysis work, we considered conducting Moreover, determined proved...

—Localizing machine type communication (MTC) devices or sensors is signi cantly important due to the increasing popularity of machine to machine (M2M) communication networks in location-based applications such as health monitoring, rescue operations, vehicle tracking, and wild re monitoring. Moreover, ef cient localization approaches for sensor-based MTC devices reduce the localization error an...

Thanks to the recent developments on communication techniques, micro-technology and on digital electronics, Underwater Wireless Sensor Networks (UWSNs) are being employed in several types of underwater applications such as wireless identification named Acoustic Frequency Identification (AFID)[1][2]. In this research, we are trying to adapt concepts of wireless acoustic identification to the dif...
