The Importance Of Saving Oceanic Environment

Introduction: The only way to save the Oceanic environment is to open up the new ways in which we learn and understand the complexity of marine life, and we can monitor waters and coasts. The key aspect for turning on the vision of saving the marine life put into reality is the availability of an effective and cooperative underwater sensing, reasoning, and communication platform. This makes possible for sensing and actuating devices to exchange data and signals, network (connect) together, collaboratively and locally asses their observation environment and act upon. The Early detection of oceanographic threats and traffic control has been recognized as one of the first priorities and effective ways in saving marine environment. However, the

TinyOS [3] is an open source, flexible, component based, and application-specific operating system designed for sensor networks. TinyOS can support concurrent programs with very low memory requirements. Contitki is a lightweight open source OS written in C for WSN sensor nodes. Contiki is a highly portable OS and it is build around an event-driven kernel. Contiki provides preemptive multitasking that can be used at the individual process level. A typical Contiki configuration consumes 2 kilobytes of RAM and 40 kilobytes of ROM. These two are the most widespread operating systems. Other operating systems developed for WSNs include MANTIS, SOS, SensorOS and

The following are some of the most important factors to consider the need of early detection of marine traffic:
• The aggressive nature of marine environment is one of the factors in which it requires greater levels of device protection.
• Allowing movement of nodes must be made for the cause of tides, waves, vessels, etc.
• It is generally necessary to cover large distances, while communications signals are attenuated due to the fact that the sea is an environment in constant motion since the energy consumption is high.
• The price of marine based WSN instrumentation is significantly higher than in the land-sited WSN.
In spite of all these negative aspects, various studies of monitoring of marine ecosystems using WSNs can be found in reviews and literatures. The solutions have in common is that they are largely designed and implemented ad-hoc (buoys, electronics and software), and oceanographic sensors and other related
