Survey on Concurrent Multipath Scheduling for Real Time Video Streaming in Wireless Network

Concurrent multipath scheduling algorithm enables efficient use bandwidth in wireless network. Multipath transport protocol provides use of multiple wireless network wi-fi, cellular network concurrently. While using bandwidth of available network channels the parameters like network path congestion, packet loss rate, etc. should have calculated accurately. Everyone wants video should be streamed smoothly for that only one network path is not capable. As mobile devices and laptops support more than one wireless network access so they can be used to stream video fast. In recent studies quality Driven multipath transport control protocol (ADMIT) uses the maximum bandwidth concurrently in wireless network. In this protocol the analytical model shows the communication between sender and receiver using forward error correction coding. The multipath protocols analyze the network properties to schedule the packets over available network paths. The sender predicts the next packet path by analyzing the previous packet delivered. The optimization strategy used to find efficient path by using the network constraints. Concurrent multipath scheduling algorithms are reduced end to end delay in the video encoding and decoding. The simulation shows the video quality required for real time video streaming is achieved by multipath scheduling algorithms. The distortion calculated is minimum shows in received frames by calculating average peak signal to noise ratio.
