Abstract: In this paper, our aim is to compare for the different wavelet-based image compression techniques. The effects of different waveletfunctions filter orders, number of decompositions, image contents and compression ratios were examined. The results of the above techniquesWDR, ASWDR, STW, SPIHT, EZW etc., were compared by using the parameters such as PSNR, MSE BPP values

Abstract: Wireless mesh network resolve the limitation of ad hoc networks which ultimately improves the performance of Ad hoc networks.

Abstract: Security system is a very essential term in wireless communication like multiple accesses. When we go through multiple access method we will find TDMA (Time Division Multiple Access), FDMA (Frequency Division Multiple Access) are working with time & frequency respectively. For security purpose TDMA and FDMA have to apply additional security features to keep those
