【摘要】：為解決當前無線傳感網(wǎng)絡(luò)數(shù)據(jù)傳輸算法的數(shù)據(jù)匯聚穩(wěn)定性不高,且難以根據(jù)鏈路抖動實時調(diào)整傳輸鏈路的不足,提出基于聚類劃分機制的無線傳感網(wǎng)絡(luò)數(shù)據(jù)傳輸算法。通過聚類劃分機制,將網(wǎng)絡(luò)中能量覆蓋水平較強的節(jié)點進行最優(yōu)聚合,實現(xiàn)最佳簇頭節(jié)點對網(wǎng)絡(luò)覆蓋區(qū)域的劃分,減輕分區(qū)內(nèi)數(shù)據(jù)匯聚的壓力;綜合考慮節(jié)點數(shù)據(jù)匯聚過程中的能量及拓撲距離對數(shù)據(jù)匯聚的影響,獲取節(jié)點傳輸過程中的距離-能量閾值,對路由進行優(yōu)化篩選,實現(xiàn)數(shù)據(jù)匯聚鏈路的動態(tài)實時更新;通過鏈路優(yōu)化篩選機制,對數(shù)據(jù)匯聚過程優(yōu)化,降低匯聚過程中的鏈路抖動。仿真結(jié)果表明,與DAAS算法、DAAS_plus算法相比,所提算法能夠降低數(shù)據(jù)鏈路的抖動,具備更高的網(wǎng)絡(luò)穩(wěn)定運行時間與更低的數(shù)據(jù)擁塞度。
[Abstract]:In order to solve the problem that the data convergence stability of the current wireless sensor network data transmission algorithm is not high, and it is difficult to adjust the transmission link according to the link jitter in real time, a data transmission algorithm based on clustering and partitioning mechanism is proposed. Through the clustering mechanism, the nodes with strong energy coverage in the network are optimally aggregated to realize the optimal cluster head node partition of the network coverage area, and to reduce the pressure of data convergence in the area. Considering the influence of energy and topological distance in the process of node data aggregation, the distance energy threshold in the process of node transmission is obtained, the route is optimized and filtered, and the dynamic real-time update of data convergence link is realized. Through the link optimization screening mechanism, the data aggregation process is optimized to reduce the link jitter in the convergence process. The simulation results show that compared with the DAAS algorithm, the proposed algorithm can reduce the jitter of the data link, and has higher stable running time and lower data congestion.
