WSNs hierarchical security model with reversibledigital watermarking

针对无线传感器网络(WSNs)资源受限与网络安全的问题,基于可逆数字水印技术,提出了一种WSNs层级安全模型。一方面通过可逆数字水印技术保障簇内数据传输的安全性;另一方面通过平衡节点剩余能量、位置信息和信任因子优化分簇策略,保障簇首节点的性能以实现网络优化管理。仿真测试结果表明:所提方案通过可逆数字水印技术可以保障数据的完整性和安全性能,达到99.95%以上的数据传输正确率,而且可以很大程度改善WSNs的能量消耗,延长网络的生存周期125%左右。

Aiming at the problem of limited resources and network security that wireless sensor networks(WSNs)has,a WSNs hierarchical security model based on reversible digital watermarking technology is proposed to ensure the safety of data transmission.On one hand,it uses reversible digital watermarking technology to ensure the security of data transmission within the cluster.On the other hand,it optimizes the clustering strategy by balancing the remaining energy,location information and trust factor of node which can guarantees the performance of the cluster head node to achieve optimization management of network.Simulation test results show that the program can ensure data integrity and security performance through reversible digital watermarking technology which can not only achieve accuracy rate data transmission of more than 99.95%,but also improve energy consumption,extend the life time of the network by about 125%.
