New emerging technologies like Multimedia applications require timely delivery of information as compared to reliability. The most widely used protocols over transport layer are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Both of these have some drawbacks while using in real time applications. TCP increases delay in transfer of data but achieving reliable transfer of data...
In VoIP (Voice over Internet Protocol) applications, packet loss affects the received speech quality greatly. PCM (Pulse Code Modulation) coders are often used for VoIP and also face such problems. In this paper a side information based packet loss recovery algorithm is proposed, which introduces a small part of corrective information to provide an enhanced reconstruction of the lost packets. A virtual...
In this paper our focus is on the performance of two new transport protocols DCCP and SCTP; the emphasis is to determine which protocol can better meet the Quality of Service (QoS) for MPEG4 video over wireless local area network. Based on results obtained in this analysis it is observed that both SCTP and DCCP achieved better throughput than UDP. For video traffic load of 4 Mbps, throughput achieved...
