Abstract [en]

One of the most important emerging aspects of Third Generation Partnership Project (3GPP) is the Multimedia Broadcast/Multicast Service (MBMS) aiming to deliver multimedia contents to mobile users more efficiently in point-to-multipoint way. 3GPP also recommends an Application Layer Forward Error Correction (AL-FEC) scheme, especially for MBMS, in order to provide reliable transmission over mobile networks. Due to many emerging FEC schemes, the existing 3GPP standardized systematic fountain Raptor code FEC scheme is considered to be outdated. One of the newly emerged codes, namely RaptorQ, has enhanced an AL-FEC scheme by providing higher protection against packet loss and superior flexibility to meet the growing demand in mobile multicast services. In this work, we provide an extensive device based performance evaluation of RaptorQ FEC codes, specified as RFC 6330 in Internet Engineering Task Force (IETF), and notice that the performance always outperforms that of the existing Raptor (RFC 5053) codes in terms of decoding speed, latency and memory. We also include the device based performance comparison of RaptorQ FEC codes in a comparison with other FEC schemes like Supercharged codes and Reed Solomon + Low Density Parity Check codes (RS+ LDPC). Finally, we conduct simulation carried out in the mobile devices for several network parameters like latency, decoding speed and memory in combination with FEC encoding and decoding parameters and investigate that RaptorQ is the best code that suits multicast services.
