No / Random packet errors and erasures are common in satellite
communications. These types of packet losses could become significant in
mobile satellite scenarios like satellite-based aeronautical communications
where mobility at very high speeds is a routine. The current adaptive coding
and modulation (ACM) schemes used in new satellite systems like the DVBRCS2
might offer some solutions to the problems posed by random packet
errors but very little or no solution to the problems of packet erasures where
packets are completely lost in transmission. The use of the current ACM
schemes to combat packet losses in a high random packet errors and erasures
environment like the satellite-based aeronautical communications will result in
very low throughput. Network coding (NC) has proved to significantly improve
throughput and thus saves bandwidth resources in such an environment. This
paper focuses on establishing how in random linear network coding (RLNC)
the satellite bandwidth utilization is affected by changing values of the
generation size, rate of packet loss and number of receivers in a satellite-based
aeronautical reliable IP multicast communication. From the simulation results,
it shows that the bandwidth utilization generally increases with increasing
generation size, rate of packet loss and number of receivers.
