Abstract
The rapid development of digital communication systems causes higher traffic in wireless networks that causes the need to get higher end videos for communication. The transmission of videos in wireless communication systems experiences intolerable delays that lead to inconsistent perception of videos. To vanquish the above stated problem the efficient zigbee protocol (IEEE 802.15.4) is used. Consequently it provides a low bit rate and low cost communications for short distances. First a method is proposed in which, the variable delays (i.e. jitter) can be reduced, by virtuously lowering the resolution of video frames. The video frames are then mixed with high resolution and low resolution frames of a sequential video. It therefore involves the efficient usage of existing bandwidths which is adopted by the behaviour of 4G networks. A further advancement hereinafter uses cryptographic techniques to provide security to the transmitted video. It includes the encryption mechanism done using elliptic curve cryptography to accomplish a secure video transmission over the WPAN (wireless personal area network) network. The final goal is to show experimental results that prove the achievement of better PSNR (peek-to-peek signal to noise ratio) and VQM (video quality metric) values for enhanced video perception.
