    摘要:

    在異構環(huán)境下無(wú)線(xiàn)傳感大數據受到網(wǎng)絡(luò )入侵影響,容易出現數據丟包率高且傳輸效率低的問(wèn)題,因此設計了異構環(huán)境下無(wú)線(xiàn)傳感大數據跨域傳輸安全控制系統。根據異構環(huán)境下無(wú)線(xiàn)傳感網(wǎng)絡(luò )結構,設計由數據采集模塊、處理模塊和顯示模塊組成的系統總體結構。選擇SY AD 08T型號數據信號采集器,監控現場(chǎng)數據采集顯示結果;使用Ryzen 3 2200G型號核心處理器支持自適應動(dòng)態(tài)擴頻,執行處理指令;通過(guò)控制電路中電壓值范圍,調節電流強度。軟件設計部分利用高維數據空間降維改進(jìn)算法,借助ELM分類(lèi)器檢測大數據跨域傳輸入侵情況,利用通信竊聽(tīng)方式添加噪聲控制接收端信噪比上限,以此控制跨域傳輸噪聲。融合信道編碼糾錯與密碼流擾亂,限制數據解碼時(shí)間,阻止非正常渠道竊聽(tīng)。在網(wǎng)絡(luò )環(huán)境和配置清單支持下進(jìn)行實(shí)驗驗證分析,由實(shí)驗結果可知,該系統丟包率低于1.5%,大數據傳輸效率最高為98%,有效增強了大數據跨域傳輸安全性。

    Abstract:

    In the heterogeneous environment, wireless sensor big data is affected by network intrusion, which is prone to problems of high data packet loss rate and low transmission efficiency. Therefore, a cross-domain transmission security control system for wireless sensor big data in a heterogeneous environment is designed. According to the structure of the wireless sensor network in a heterogeneous environment, the overall structure of the system composed of data acquisition module, processing module and display module is designed. Select the SY AD 08T model data signal collector to monitor the on-site data acquisition display results; use the Ryzen 3 2200G model core processor to support adaptive dynamic spread spectrum, execute processing instructions; adjust the current intensity by controlling the voltage value range in the circuit. The software design part uses the improved algorithm of high-dimensional data space dimensionality reduction, uses the ELM classifier to detect the intrusion of large data cross-domain transmission, and uses communication eavesdropping to add noise to control the upper limit of the signal-to-noise ratio at the receiving end to control cross-domain transmission noise. Fusion of channel coding error correction and cipher stream disruption limits data decoding time and prevents abnormal channels from eavesdropping. The experimental verification analysis was carried out under the support of the network environment and configuration list. From the experimental results, it can be seen that the system's packet loss rate is less than 1.5%, and the maximum data transmission efficiency is 98%, which effectively enhances the security of large data cross-domain transmission.
