摘　　要：当前节点位置信息驱动的无线传感器网络节点部署不合理,造成目标区域存在大量覆盖盲区,驱动时间较长的问题。据此,设计并提出物联网终端密集场景缓存节点位置信息驱动方法。假设整个物联网传感器网络被划分称为多个宽度可变的环带,网络中全部节点的通信都能够进行调整。通过相关推导获取单位时间内平均能耗的计算式,得到最内层环的最佳环带宽度,实现物联网终端密集场景缓存节点位置信息驱动。经实验分析,所提方法与其它文献方法相比,目标区域覆盖率较大,驱动时间较短。The deployment structure of nodes in wireless sensor network driven by current location information is unreasonable,resulting in a large number of coverage holes in target area.Therefore,a location information driven method for cache node in IoT terminal dense scene was designed.If the whole IoT sensor network was divided into many ring belts with variable width,the communication of all nodes in network could be adjusted.Based on relevant derivation,the formula of average energy consumption per unit time was obtained,and the optimal width of loop in innermost layer was found.Finally,the location information of cache node in IoT terminal dense scene was driven.According to simulation analysis,we can see that the proposed method has larger coverage rate and shorter driving time.
