Technological growth in the digital communication era made a huge impact on life style of human beings. Now a day the growth of social networking sites gained much popularity around the world. Social networks provide a means for users to interact or communicate over the internet. Some of the trending social media include Facebook, twitter, WhatsApp, LinkedIn, Instagram, google+ and so on. The multimedia data is the basic building blocks for all the types of communications. Social networks also help to share multimedia data like audios, videos, stories and animations. Users can access these social media services via web-based tools through laptops, smart phones and tablets. Social networks are extremely communicating stages through which persons, groups and governments can share, co-create, discuss and modify the data through internet. In this paper the different video processing models in MANETs such as Prediction Model, Network Friendly Model, Congestion Control Model and Bandwidth Estimation Model are critically analyzed. By varying the impairments these models are compared using a network simulator.

The tremendous development in wireless technologies and multimedia applications persuaded upsurge in spectrum utilization in the past. One of the adequate clarifications to overwhelm this limitation is by using Cognitive Radios (CR). These networks are likely to boost spectrum consumption professionally by permitting Secondary Users (SUs) to take advantage of the use of the approved spectrum of primary users (PUs). CR is a kind of a sensible radio that can sense the extraneous surroundings, analyze the past and build perspicacious conclusions to switch its transmission factors in step with the current state of the atmosphere. An Ad-hoc Network engaging Cognitive Radios (CR) can often be termed as Cognitive Radio Adhoc Network (CRAHN). Routing in CRAHN is not an easy mission due to spectrum availability, power, link stability, etc. Among all the parameters, the one among the best parameter for route selection is throughput. Since several applications need a high value of throughput like Audio & Video Broadcasting, Interactive audio & Video Streaming, etc. and some require the low value of throughput like E-mail, Telnet, etc. This paper design a routing strategy based on finding an optimal throughput path using fuzzy logic. To show the efficiency of a designed scheme it is compared with the shortest path routing mechanism. Our result shows that the proposed method is efficient than Shortest Spectrum.
