摘　　要：在多信道环境下传输数据,易受无线通信网络连接不稳定性影响,且存在多个节点竞争同一资源的情况,导致数据冲突,影响数据存储的完整性。为此,提出一种多信道无线通信网络动态数据完整性存储方法。通过计算节点发送与接收的能耗,利用层次聚类算法,结合密度对网络监测区域内全部节点分簇处理,获取感知数据集合,采用最小二乘法采集动态数据,利用优化的谱哈希算法将高维网络动态数据映射为哈希码,利用基于柯西分布的哈希映射,得到概率密度函数,根据映射值间距,实现多信道无线通信网络动态数据完整性存储。通过仿真表明,所提方法的丢包率取值一直处于2%以下,吞吐率逐渐接近于98%,资源占用率最高仅为14.6%,可以获取满意的网络动态数据完整性存储结果。When data is transmitted in multiple channels,it is easily affected by the inst ability of wireless communication network connection,and there are multiple nodes competing for the same resour ce,leading to data conflicts and affecting the integrity of data storage.Therefore,this article presented a storage m ethod for dynamic data integrity in multi-channel wireless communication net works.Firstly,we calculated the energy cons umption of sending and receiving nodes,and then used the hierarchical clustering algorithm to cluster all nodes in the network monitoring area in combination with the density,thus obtaini ng the perceptual data set.Secondly,we coll ected dynamic data by the least square method.Meanwhile,we mapped the dynamic data in high-dimensional networks to the hash code by the optimized spectral hash algorithm.Moreover,we adopted the hash mapping method based on Cauchy distribution to calculate the probability density function.According to the mapping interval,we realized the dynamic data integrity storage in multi-channel wireless communica tion networks.Simulation results prove that the packet loss rate of the proposed method is always less than 2%,the th roughput rate is gradually close to 98%,and t he highest resource usage is only 14.6%,so we can obtain satisfactory results of network dynamic data integrity sto rage.
