无线传感器网络中基于网络编码的容错路由

Fault Tolerant Routing Based on Network Coding in Wireless Sensor Network

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.

Towards the influence of the nodeeavesdropping and embezzling in wireless sensor network, we propose a fault-tolerant routing based on network coding（FR-NC）. FR-NC utilizes election to ensure the data coherence while considering the characteristic of majority correction rule. As a result, it can resist tampering efficiently. On the other side, we encrypt date with random coding parameter to protect and monitor the data security. Finally, through the a- nalysis of experiment results, we can find that FR-NC has good performance when amount of malicious nodes exist in wireless sensor network.
