It is difficult to serve mobile users in dense MANET (Mobile Ad-hoc Network) by selecting traditional infrastructure of Ad-hoc networks. Mobile multimedia in pervasive environments often targets dynamic mobile ad hoc networks (MANETS) with densely populated areas of interest In this project, we proposed new relay based technology to handover from old relay node to new relay node. For this purpose, we use implementation of ad-hoc mobile nodes with radio channel in Matlab platform by multimedia data i.e. Image. We have simulated this scenario against RSSI (Received Signal Strength Indication) and PSNR (Peak to Signal Noise Ratio) by considering more than 15 mobile nodes. Based on RSSI and PSNR values, we have decided the threshold to handover to the new relay node from old relay node. In this way, we have saved the bandwidth and spectrum as well as we noticed there is increase in multimedia data throughput with less congestion in network.

Now days there is huge amount of advancement going on in the integrated circuitry technology. With this improvement the computational devices become smaller, faster and cheaper. Along with the growing wireless communication technology, a new networking model has been introduced which is nothing but wireless sensor network. It draws much attention from researchers and industries in recent years because it provides an extraordinary application scope for users and challenges for researchers.
