Ns2 Video Streaming Projects

Ns2 Video Streaming Projects – How to create Video-Streaming Projects using Ns2.

What is video-streaming?

• Streaming-media is video-data transmitted over a computer network for immediate playback rather than for file download and later (offline) playback.
• Examples of streaming-video include Internet television broadcasts, and corporate webcasts.

Challenges Faced in video-projects:

• Power control system.
• Scheduling for video streaming.
• Traffic modeling and prediction for video-scheduling.
• Congestion coherence.
• Server replication.
• Multiple descriptive coding etc.

Benefits of Ns-2 Video Projects

• Can control your messages.
• Can be very engaging.
• There is no need for waiting until completion of downloading the videos.
• Instant playback.
• Privacy protection.
• Reaching out to a real-time audience who has opted-in to watch.

Sample Ns-2-code for Video-streaming Projects

#include "ns-process.h"

{
	abort();
}

void Process::process_data_buffer(int, AppData*,int,int)
{
	printf("hola1 process\n");
	abort();
	printf("hola2");
}


AppData* Process::get_data(int&, AppData*)
{
	abort();
	/* NOTREACHED */
	return NULL; // Make msvc happy 
}

					argv[2]);
				abort();
			}
			target() = p;
			return TCL_OK;
		}
	}	return TclObject::command(argc, argv);}
