To this direction, the use of forward error correction (FEC)&nbsp;on the application layer is widely adopted in several mobile multicast standards. FEC is a feedback free error control method, where the transmitter&nbsp;introduces in advance redundant information within the source data to enable receivers recovering arbitrary data erasures. On multicast delivery where&nbsp;retransmission-based error recovery methods are not ecient, the most suitable error control method is the use of application layer forward error correction (AL-FEC) codes. In this work, we introduce novel AL-FEC deployment&nbsp;policies over mobile multicast environments utilizing online algorithms. We&nbsp;aim at the ecient application of AL-FEC protection with RaptorQ codes over multicast delivery in the context of competitive analysis. We provide a&nbsp;competitiveness analysis model of AL-FEC application over mobile multicast&nbsp;environments. Furthermore, we propose two online algorithms adjusting the introduced redundancy of AL-FEC protection according to several FEC encoding parameters and constraints of mobile multicast delivery.</p>
