摘　　要：应用在不同环境下的栅栏覆盖会受到时间、距离以及最低置信度等约束条件的影响,导致覆盖漏洞较多,为提高覆盖质量,提出基于云安全架构的机器人无线传感器网络栅栏覆盖设计。首先,分析云安全防护技术,确立云计算安全架构,分别设置数据管理、加密、备份以及储存地点等模块;其次,建立无线传感器网络模型,探究网络节点结构,把大量节点部署在检测目标区域内并与网络相连,将网络构建成本与生存时间作为栅栏覆盖的评价指标;最后,构建物理、协议抗干扰模型,预测通信链路之间是否存在干扰,利用迪杰斯特拉算法检测覆盖漏洞,选取节点分布密集区域作为漏洞修复区域,将漏洞问题转换为平面几何问题,经过节点重新部署达到理想覆盖设计效果。仿真结果表明,所提方法有效提升覆盖质量,减少网络计算量,进而延长网络寿命。The fence coverage applied in different eiwironments will be affected by time,distance and the lowest confidence,resulting in many coverage vulnerzheabilities.In order to improve the coverage quality,this paper proposes a fence coverage design based on cloud security architecture for robot wireless sensor network.First of all,analyze the cloud security protection technology,establish the cloud computing security architecture,respectively set up data management,encryption,backup and storage location modules;second,establish the wireless sensor network model,explore the network node structure,deploy a large number of nodes in the detection target area and connect with the network,and take the network construction cost and survival time as the evaluation index offence coverage At last,the physical and protocol anti-inteiference models are built to predict whether there is interference between communication links.The Dykstra algorithm is used to detect coverage vulnerabilities,and the densely distributed area of nodes is selected as the vulnerability repair area.The vulnerability problem is transformed into a plane geometry problem,and the ideal coverage design effect is achieved through node redeployment.Simulation results show that the proposed method can effectively improve the coverage quality,reduce the amount cf network computing,and then extend the network lifetime.
