OPTIMAL DEPLOYEMENT OF WIRELESS SENSOR NODES

Abstract

The arena of underwater communication has developed a great deal in the last decade or so. Innovative ideas and techniques are being adopted, the use of WSNs is the topic of interest specifically. Wireless sensor nodes (WSNs) are deployed in an open or indoor region in order to collect information. As, obviously, that underwater communication and the WSNs are provoked by harsh environment so in this regard the deployment plays an important role. The type of deployment determines all the important parameters and results of the system or network. As WSNs are battery operated and in the mid of an ocean in deep sea it’s not possible to replace the battery manually. Routing Protocols have been designed from time to time but an effective deployment can make the performance of network even more when incorporated with a routing protocol Therefore, the deployment schemes is proposed and is incorporated with “Greedy Algorithm to improve the Network Lifetime, packet delivery ratio and makes our network reliable. In past the researchers have intensely worked on different deployment schemes in order to solve energy consumption issue, since they have missed out on some of the important parameters which can be combined to deployment, which I find as my research gap. In this research an optimum deployment scheme based on Temperature, Salinity and pressure is presented. The desired area is divided into four layers on the basis of changing Temperature, Salinity and pressure with respect to depth. According to the proposed technique 15 percent nodes are deployed at the top,20 percent in layer two,25 percent in layer three and 40 percent in layer 4. The aim is to somehow extendthe lifetime of the network, and assure the packet delivery.
