Underwater wireless sensor networks are significantly different from terrestrial sensor networks in which sound is mainly used as the communication medium. This paper reviews the main challenges caused by the underwater environment for the development of efficient under water sensor networking solutions and introduces several novel medium access control (MAC) protocols with power control to increase efficiency and save on energy.
Underwater wireless sensor networks (UWSN) has received growing interest recently. It has many applications potentially in ocean graphic data collection, water quality monitoring, surveillance purposes and national security purposes. UWSN consist of a certain number of sensors that interact to send data to the onshore or surface sink node and perform collaborative tasks. Different applications have different reliability requirements. Thus data reliability is one of the most important requirements for data transmission. However, it would be a challenging task to assure reliable data delivery between the sensor nodes and the sink node, because the network performance is subject to the limitations and constraints of the complex underwater environment.
In this paper review, the main challenges of the UWSN MAC protocol design are introduced. Then the related works of existing reliable MAC protocols for UWSN are reviewed and summarized.
II. Challenges of MAC protocol for UWSN
Compared to radio waves used in terrestrial sensor networks, which would have very high attenuation underwater, acoustic waves has better propagation characteristics in water, making it the preferred method for underwater communications. Hence acoustic channel is used as a link for communication in underwater sensor...

- The purpose of the literature review is to identify and highlight the important variables, and to document the significant findings from earlier research that will serve as the foundation on which the conceptual or theoretical framework for the current investigation can be based and the hypotheses developed (Cavana, Delahaye & Sekaran 2000). This stage is important to convince the reader that the researcher is knowledgeable about the problem area and has done the preliminary groundwork to conduct the research, and also that the conceptual framework will be built on the solid foundation of existing knowledge The literature review has emphasised on the importance of four major and common facto...

- The basis of good character involves being respectful, honest, hardworking, responsible, caring, and understanding. Parents and teachers alike wish for their students to possess good character; but what does “character” mean in the realm of education; and whose responsibility is it to ensure that students do in fact develop good character. The Character Education Partnership (2003, pg. 1), defines good character as involving “understanding, caring about, and acting upon core ethical values”, and thus takes a holistic approach to the development of character in students by developing the “cognitive, emotional, and behavioral aspects of moral life.” Through character education, students can gr...

- This literature review of twelve previously published research articles has focused on summarizing some of the effects of poverty on children. The selected articles all focused on the major effect of poverty on children, and were sorted into four sub-categories or themes based upon a specific focus areas of this complex and not yet fully understood issue. These themes included developmental, educational outcomes, health, and parenting effects, and how they were impacted by children living in poverty.... [tags: Literature Review]

- UNDERWATER WIRELESS COMMUNICATION The communication between any two entities can be either wired or wireless. The concept of wireless technology was started in the year 1923. As we all know that 70% of the earth is full covered with water. It was necessary to develop wireless network that can also work under water. Here arises the concept of acoustic waves. Acoustic wave’s works better in water .Also it can travel long distance inside water and are very fast than radio waves. The concept of underwater wireless communication is a major finding in the field of wireless communications.... [tags: messages, oceanography, transmitting]

- Introduction Educators attempt to provide safe, nurturing environments where students can thrive. Any disturbance to this climate can have negative affects on students’ educational performances. Bullying is one such disruption. Unfortunately, physical and verbal abuse are nothing new in the school setting, however, the rise of technology in our country has created a new setting for bullies to target their victims.

- A considerable amount of literature has been published on cannabis specifically marijuana. These studies classify marijuana into three species: Cannabis sativa, Cannabis indica, and cannabis ruderalis. In fact, Cannabis sativa is the most widely used and recognized among the other species due to its ability to produce more fiber and oil. For many years, the plant has been used for making clothes as well as lighting and soap. Nevertheless, cannabis is widely used at the present time for intoxication and medical treatments....

- Literature Review of 5 articles Based on secondary research of articles that our group had conducted, it led us to the problem statement that quality does not meet price. We accumulated five significant articles and utilized its information in order to generate the problem statement. What we noticed is that there were a lot of articles regarding quality issues related to Sony laptops. This made us question the high prices of Sony's offerings. The first article, entitled “Sony shares drop after VAIO recall," from the New York Times talked about the consequence of the 438,000 units of VAIO TZ laptops that were recalled last year....

- Forensic Psychology, which is occasionally referred to as Legal Psychology, originally made its debut in the late 1800’s. A Harvard Professor, Professor Munsterberg, introduced the idea of psychology and law with his book, On the Witness Stand in 1908. Since the inception of the idea of psychology and law there have been proponents, as well as though that have spoken against the theories proposed by Munsterberg’s, along with other scientists, theorists, and psychologists that believed that Forensic Psychology had no standing to be linked to topics of law....
