    摘要:

    無(wú)線(xiàn)傳感網(wǎng)作為一個(gè)重要的數據調度工具,是人類(lèi)同自然交互的有效途徑。然而,無(wú)線(xiàn)傳感網(wǎng)中的傳感器數量有限,同時(shí)還極易被無(wú)關(guān)因素影響。因此,研究提出一種基于區間二型TSK模糊系統和高效數據融合的非均勻分簇路由算法,分簇是為了最大程度地減小網(wǎng)絡(luò )損耗,延長(cháng)其生存時(shí)間,一般的分簇方法,可能會(huì )導致負載失衡,為解決這種熱區現象,研究使用區間二型TSK模糊邏輯算法,進(jìn)行非均勻分級分簇。同時(shí)引入高效數據融合技術(shù),將調度過(guò)程劃分為幾個(gè)周期,利用時(shí)間間隙進(jìn)行數據采集,并進(jìn)行降維操作,進(jìn)一步提升數據傳輸效率。研究在MATLAB平臺,對該算法以及自適應分簇層次等其余四種算法進(jìn)行對照分析實(shí)驗,并將其分為200m×200m和1000m×1000m的監測范圍,實(shí)驗結果表明,在不同大小的監測區域中,研究使用算法的分簇效果、網(wǎng)絡(luò )吞吐量以及節點(diǎn)損耗率指標,都明顯優(yōu)于其他算法。其中,在小范圍區域內,其剩余能力均值比自適應分簇層次算法提升了49.7%;在大范圍區域內,該算法的HND指標比自適應分簇層次算法提升了98.7%。因此,研究采用算法具有極佳的性能。

    Abstract:

    As an important data scheduling tool, wireless sensor network is an effective way for human to interact with nature. However, the number of sensors in wireless sensor networks is limited and easily affected by irrelevant factors. Therefore, this paper proposes a non-uniform clustering routing algorithm based on the interval type-2 TSK fuzzy system and efficient data fusion. The clustering is to minimize network losses to the greatest extent and extend its life time. The general clustering method may lead to load imbalance. Heterogeneous classification and clustering were performed. At the same time, the efficient data fusion technology is introduced to divide the scheduling process into several cycles, use the time gap for data acquisition, and reduce the dimension operation to further improve the efficiency of data transmission. On the MATLAB platform, this algorithm and the other four algorithms, such as adaptive clustering level, are analyzed and tested, and they are divided into monitoring ranges of 200m×200m and 1000m×1000m. The experimental results show that in monitoring areas of different sizes, the clustering effect, network throughput and node loss rate indexes of the algorithm used in the study are as follows: Are obviously due to other algorithms. In a small range, the average residual capability of the algorithm is improved by 49.7% compared with the adaptive clustering hierarchical algorithm. In a large range, the HND index of the proposed algorithm is improved by 98.7% compared with the adaptive clustering hierarchical algorithm. Therefore, the algorithm adopted in this study has excellent performance.
