基于网络编码的WSN可靠数据分发方法
A WSN reliable data dissemination method based on network coding
摘要
Abstract
A network coding based reliable data dissemination method for wireless sensor network was presented. The key idea of the proposed method is to combine random linear network coding (RLNC) and flooding protocol to realize the function of data dissemination. To solve the problem that destination node cannot receive all the data due to the collision of data transmission, we mainly discussed reliable retransmission mechanism aiming for 100% dissemination success ratio. Through simulation experiments, on one hand, the effect of the proposed method on network performance was analyzed, which is favorable for the optimization of network parameters. On the other hand, we verified that the proposed method enhanced the reliability of data dissemination, which could reduce the number of packets sent by sink node and thus realize the power saving of wireless sensor network.关键词
