EFFICIENT LOCALIZATION SCHEMES FOR IMPROVING THE SIGNAL STRENGTH AND SECURITY IN WIRELESS SENSOR NETWORKS

Abstract

The first level of the work has been analyzed with various frequencies in newlinethe communication channel newlineThe channel has been measured with Space Division Multiple Access SDMA Frequency Division Multiple Access FDMA and newlineOrthogonal Frequency Division Multiple Access OFDMA newlineThese techniques help us to provide the channel efficiency and high bandwidth for establishing the Quality of Service QoS newlineThe comparison has been carried out with these three techniques and then QoS has been produced with OFDMA technique newlineThe OFDMA is best technique for providing the higher throughput with utilization of newlinemaximum number of bandwidth newlineThe communication channel is assigned newlinebetween the networks the position should be finding with help of Particle Swarm Optimization PSO technique newline This technique is used to find the signal position in the localization newlineThe frequencies are measured in the particular position in terms newlineof signals which is finding in the location newline
