摘要:
 为了减少在无线传感网络中数据的重传次数，提高无线传感网的数据传输效率，提高服务质量，文中提出了一种网络编码的广播算法( WMBR)。在该算法中，依据网络接收节点的丢包情况，创建生成丢包的哈希表，选择并生成高效的重传数据包，然后对数据包再进行二次编码，通过这种方法有效地提高了重传效率。经过软件的仿真，结果表明：相比于普通重传方法及现有的算法而言，这种方法能够有效地降低数据包的重传次数，提高了无线传感网中数据通信的效率。
Abstract:
 In order to decrease the number of retransmission for wireless sensor network,improve the data transmission efficiency for WSN and service quality,put forward a WBMR in this paper. According to the receiving node packet loss situation,create a lost package hash table,select and generate efficient retransmission packets,again for a second coding,thereby improving the efficiency of the retransmis-sion. The simulation results show that compared with ordinary retransmission method and the existing algorithms,this method can effec-tively reduce the retransmission times and improve the efficiency of data communication in WSN.
