| 摘 要： | 为了提高无线网络中数据包广播传输的效率,本文提出了一种基于机会式网络编码的广播传输算法.该算法在发送端按一定顺序选择不同终端的丢包,并采用异或运算编码重传包,在终端采用从重传包中解码数据包的方法恢复丢包.该算法优先恢复时间重要性较高的丢包,并使多个终端同时从单个重传包恢复其丢包,因此有效地提高了广播传输效率并降低了传输...

| Abstract: | An opportunistic network coding based broadcast transmission algorithm(ONCBT) is proposed to improve the transmission efficiency for wireless networks.ONCBT selects lost packets in a sorted order to generate the retransmission packet by XOR operations at sender,and retrieves lost packets from one or more retransmission packets at receivers.ONCBT has a priority to retrieve the lost packets owning higher time important level in each receiver with one retransmission packet,thus improving the transmission effic... |
