摘要
研究了一种新的信誉评测模型,模型采用"加法奖励、乘法惩罚"的方法。该模型与现有模型相比,运算简单,资源消耗少,适合于无线传感器网络节点资源受限的特点。仿真实验表明,该模型可以快速降低实施不良通信行为节点的信任值,从原理上减少误判。该模型为无线传感器网络路由协议设计提供了新的选路依据。
A reputation model of sensor nodes in WSNs named AEMP was proposed. AEMP mearks ＇Addition Encoura- gement, Multiplication Punishment＇. Compared with current other models, AEMP can work with simple calculation and need fewer resources. So it is fit for the character that sensor nodes in WSNs have limited resources. Emulation experi- ments show the model can depress the reputation value of the node that executes bad communication behaviors quickly. And it can also reduce the possibility of wrong judgment. The mode affords a new routing algorithm for designing a WSNs routing protocol.
