Abstract:
Network coding was the major improvement for packet retransmission schemes in wireless multicast broadcast services (MBS). In the existing system the researchers use three main schemes: ONCR (Opportunistic network coding retransmission), FNCR (Full network coding retransmission) and ANCR (Adaptive network coding retransmission). First two schemes are not efficient because, in ONCR it will transmit the packets which are not intent to send to the receiver. In FNCR, it decreases the bandwidth efficiency because of re-transmitting all the packets in addition with the required packets. In order to overcome the above drawbacks, Adaptive network coded schemes are used to improve the bandwidth efficiency in MBS using a combination of opportunistic and full network coded re-transmission. It can be applied for the single-hop wireless broadcast services. In the proposed system, this transmission scheme is applied for the multi-hop wireless broadcast service. It has the advantage of more effective bandwidth usage and in reducing the re-transmission.
