传统的无线网络相关研究都是基于理想化的单位圆模型。该模型的一个明显的特点就是节点间链路的存在与否具有一定的随机性,但是它的局限性在于没有对链路存在的强弱程度予以刻画,因此不能很好的反应实际情况。该文提出了一种模糊单位圆网络模型,通过引入链路模糊机制,有效的改进了单位圆模型中由于概率表征本身不完备的情况下带来的描述局限性问题。最后在AODV,DSDV,DSR等常用路由协议的基础上对该模型进行了模拟,并对比分析了两种模型在网络生命期以及能量消耗速率等参数的变化情况。
In traditional wireless network research area,the most study is on ideal unit disk model(UDM).The common characteristic in this model is the link existence is random according to some distribution.But,the shortcoming of it is that the strength of link does not describe and can not reflect the true environment.So this paper tries to put out a fuzzy network model(FUDM),utilizes the link fuzzy metric and solves the inability of probabilistic model that born on earth.The paper simulated the FUDM model under the usual routing protocol AODV,DSDV,DSR.The difference of the network lifetime and energy consumption rate is analyzed.
