multicast services is the enhanced reliability by means of advanced
error control schemes. To this direction Third Generation
Partnership Project (3GPP) has standardized exclusively for
Multimedia Broadcast/Multicast Services (MBMS) the use of a
Forward Error Correction (FEC) mechanism on the application
layer based on Raptor codes. Since the standardized systematic,
fountain Raptor code is now considered obsolete, the emergence
of a new variant of Raptor codes, named RaptorQ, provides
enhanced capabilities for mobile multicast services. In this paper,
we provide a performance comparison of the standardized
Raptor Application Layer FEC (AL-FEC) scheme with the very
promising RaptorQ FEC code. We examine the enhancements
that RaptorQ introduces on the AL-FEC protection robustness,
providing a thorough performance analysis in comparison with
the current Raptor FEC scheme. Furthermore, in order to
verify the improved performance of RaptorQ, we provide several
simulation results utilizing the ns-3 environment, considering the
application of both the examined AL-FEC schemes over multicast
services for next generation mobile networks.10aFEC10aLTE10aMBMS1 aBouras, Christos1 aPapazois, Andreas1 aKokkinos, Vasileios1 aKanakis, Nikos  uhttp://telematics.upatras.gr/telematics/publications/enhaning-reliable-mobile-multicasting-raptorq-fec?language=el
