针对无线传感器网络中节点被窃听和盗用对数据安全传输所带来的影响,提出了一种基于网络编码的容错路由(fault-tolerant routing based on network coding,FR-NC).该路由算法利用网络中大多数节点能正确传输数据的特点,通过选举保证数据一致性,从而防止了盗用节点对数据的篡改;同时对随机编码系数进行加密,起到了对数据安全的监督和保护作用.通过对实验结果的分析,可以发现当网络中存在一定数量的盗用节点时,FR-NC具有较好的健壮性.
Aiming at the effect of node eavesdropping and stealing on data security transmission in wireless sensor network, a fault-tolerant routing based on network coding (FR-NC) is proposed. The routing algorithm uses network Most of the nodes can correctly transmit data characteristics, ensure the data consistency through the election, thereby preventing the theft node data tampering; at the same time, the random coding coefficient is encrypted, played a data security supervision and protection.Through the experiment The analysis of the results shows that FR-NC has better robustness when there are a certain number of theft nodes in the network.
