In present day to day life, effective data hiding methods are needed due to attack made on data communication. This paper presents the technique for the above requirement. In this proposed method, secret message in form of audio file is embedded within another carrier audio file (.wav) .In the transmitter end the output will be similar to the carrier with(More)
Intellectual mobile terminals (or users) of next generation wireless networks are expected to initiate/Establish voice over IP (VoIP) calls using session set-up protocols like H. 323 or SIP (Session Initialized Protocols). To provide quality metrics of video conferences, telemedicine and other voice over broadband telephony (VoBB) applications. In this(More)
A 4G systems can provide a comprehensive IP based solution where voice, data, video streamed multimedia can be provided to users on an "Anytime, Anywhere" The aim of the work is to estimate quality of metric values with different IEEE 802. 11 standards (IEEE 802. 11. b. /a/g), utilized for SIP (Session initialized protocol) video call setup(More)

A 3GHz class of an EF and U shaped Microstrip Patch Antennas (MPAs) designed, simulated and fabricated has been presented in this paper. These simulated designs with appropriate parameters are implemented on the fabrication prototypes which have been validated with help of Agilent Microwave Analyzer (N99917A). These proposed MPAs and dielectric equivalent(More)
