【摘要】 在MANETs中拥有大量的发送节点和接收节点,数据包发送成功率较低,而随着移动性的增加,数据包的发送成功率会变得更小。因此,无线Ad hoc网络中数据包的可靠传输需要性能较好的组播重传机制来支持。本文提出一种基于网络编码的ARQ重传机制,并利用CLONE-K-LOOP算法优化组合需要重传的数据包,减少重传次数,同时也保证了重传的可靠性。实验结果表明,基于网络编码的重传机制相对传统的重传机制在重传次数上明显的减少。更多还原

【Abstract】 In MANETs,due to the large number of sending nodes and receiving nodes,the success rate of sending packets is low.And as the increase of the mobility,the success rate becomes lower.So,the reliable transmission of the packet in the mobile Ad hoc network needs the support of the better performance multicast retransmission mechanism.In this paper,we propose an ARQ retransmission mechanism based on network coding.And use the CLONE-K-LOOP algorithm to optimized combine the packets which need to retransmit,which can reduce the retransmission number and ensure the reliability of the retransmission. The results show that,contrast to traditional retransmission mechanism,our method has significantly reduced in retransmission number.更多还原
