Abstract & Overview
Firstly it is needed to realize Wireless Sensors Networks (WSN); we can define it as the most important technologies in the new century. during the last decades there was many achievements especially in the field of micro sensor technology and the low power electronics have made WSNs and the reality of applications, WSNs enabled a great amount of the surveillance and supervision applications, especially for the hostile and the critical environments, such as the process of monitoring the sea. We are presented software and hardware platforms of the augmented sensor networks which should be connected in a temporal way to the back-end infrastructures to store the data storage and the interaction of the users, and it make a special use for the actuators or the devices which are considered a rich and special computing resource to manage a complex signal processing tasks. In our proposed solution, we attempt to deploy the sensors of the network which is used on the sea surface shall monitor the water characteristics such as temperature, PH, dissolved oxygen, etc., and provide various convenient services for end users who can manage the data via a website with spreadsheet from a long distance or applications in a console terminal. This project introduces the architecture of a WSN system, the hardware of the node, data acquisition, data processing with gateway, and data visualization. The schemes which are considered traditional one depend on the intensive work of the labor and the expensive hardware. We presented better solutions with special sensors to measure the characteristics of the water in Kuwait. stored in a SQLite3 database. At the same time, the environment can be monitored and controlled remotely via a website or applications in a console terminal. The next parts of this paper are ordered as follows. Section 2 presents the problem statement. Section 3 briefly describes the related works. Section 4 overviews the design of Water Monitoring System with three layers (Physical, Network and Application). Section 5 describes the implementation of system. Section 6 reports the experimental results. Finally, Section 7 concludes the paper with a discussion of future works. II. PROBLEM DESCRIPTION We are going to discuss what happened during Sep. and Aug. of 2001, The Kuwaiti Bay, the embayment is enclosed to the Arabian Gulf it is experienced that there is a great fish and those fishes are considered a killer fishes, it is involving more than 2500 metric tonne of the savage mullet, because of the spherical Gram positive bacteria. In the Kuwaiti Bay, this issue had been preceded by the small killing fishes (one hundred to one thousand fish in the day) of podlanica sea bream in the aquaculture net pens which is connected to the bloom of Ceratium furca which is considered one of the species of the marine dinoflagellate. Sea bream had been found and considered a positive culture for the S. agalactiae, but didn’t provide us with any obvious signs of the disease. Uncommonly the temperature of the warm was (more than 35 °C) and the conditions of the calm had been overcome during this time. As the severe kill fish had been progressed, different kinds of the harmful algae were visible for the people, such as the Gyrodinium impudicum, catenatum, Pyrodinium bahamense var and compressum. The number of the Cell especially G. catenatum G. impudicum had been elevated to reach 1006 l−1 in different positions. All fish tested below the limits of detection for (P.S.P) ‘The syndrome of shellfish poisoning’ and. the Clams were considered positive for the syndrome of shellfish poisoning but at some of the below levels it had a regulatory limits. The inorganic and the organic nutrient concentrations were variable with the time and the location (from place to another) to reflect the inputs from sewage outfalls, the operations of the aquaculture, the high biomass of the disintegrate fish, and other resources. It was hypothesized which there are several factors had participated in the primary outbreak of the disease that leaded from the bacteria, such as the unusual warm and the calm condition. These factors which enriched nutrient condition which appear obviously were conducive to the succeeding H.A.B outbreaks. The detection of P.S.P (The syndrome of shellfish poisoning’), while we found a below regulatory limit, to warrant another monitoring system to let the human health in the safe side to solve such a problem, Kuwait authorities started to monitor the water’s characteristics. The installed solution requires personnel to physically go and take the readings from different places across Kuwait Bay and bring back the data to be processed. Such a procedure is considered to be cost inefficient in terms of effort and time, and human error is strongly involved. Rather than spending hours on training, the team should do the reading tasks.
