Comparative Study of UDP and TCP Protocols for Multipath Multicasting Video in Manets
Kanmani Ruby · 2012
The main objective of this work is to split the video into multiple parts and send each part over a different path based on the amount of traffic in each path. Traditionally UDP protocols were being used for the transmission since they do not have acknowledgements. UDP is used since real time traffic uses RTP protocol for multimedia transmission. TCP is a connection oriented protocol not suited for delay sensitive transmissions .In this paper, the TCP protocol has been modified with an efficient congestion control algorithm. In this algorithm, the congestion window limit is determined based on the four parameters like short term throughput, packet out of order arrival, inter-arrival time and packet loss ratio. The performance study has been done with these UDP and Modified TCP protocols by multipath multicasting video over MANETS.
