dc.description.abstract | In this thesis, we propose a cloud-assisted network coded packet retransmission approach to reduce the number of packet retransmission based on network coding and software-define network (SDN) in wireless multicasting. It is shown that the efficiency of packet retransmission can be significantly improved if we include network topology information (e.g., network connectivity) during the encoding process of network coding. We leverages the capability of software-defined networking (SDN) to dynamically monitor and control the entire network and design a network topology based network coded packet retransmission (NTNCPR) mechanism. The proposed NTNCPR mechanism can easily calculate the good packet combination based on network topology information, and avoid the packet collision or network congestion caused by redundant retransmission packets or crowded network. Our simulation result shows that the proposed approach can significantly reduce the number of packet retransmission for different number of uncoded packets, number of nodes and packet loss probability. Furthermore, our power consumption experiment shows that the proposed mechanism can reduce the retransmission times efficiently and keeping save the power consumption at the same time. | zh_TW |
