sink node 中文意思是什麼
sink node
解釋
最終點-
Network nodes are divided into clusters in geocrp, sensor nodes send data to their cluster heads and these data are transferred between cluster heads until they reach the sink node, such a hierarchical network structure can increase scalability of the network
Geocrp將網路中的節點劃分成簇，感知節點採集的數據首先傳送到其所在簇的簇頭，再通過簇頭之間的通信進行簇間中繼，直到到達匯聚節點。 -
Third, draw a unilateral line from every load node to the sink point. the line ' s capacity is the load value of the node and the cost is zero
從所有負荷節點到匯點各引一條單向弧，弧容量為節點負荷值，弧費用為零。 -
First, suppose a source point and a sink point. second, draw a unilateral line from source point to every substation node. the line ' s capacity is set as corresponding substation ' s allowable load value and the line cost is set as the substation ' s unit load cost
本文通過線性化處理后將網架優化模型描述為一個最小費用最大流問題，虛擬一個源點和一個匯點，從源點到各變電站節點各引一條單向弧，弧容量為變電站允許的負荷值，弧費用為變電站單位負荷的費用。 -
Abstract by setting up a network model of data aggregation and using a bit - hop metric to quantify energy costs in wireless sensor networks, we formally analyze the problem of area - based data aggregation and obtain that data aggregation will definitely be energy efficient when the relative difference between the average lengths of the two shortest paths, which are from source sensor nodes to the sink and to the aggregation node respectively, is not less than the ratio of data correlation to the number of source sensor nodes
摘要通過抽象出無線傳感器網路中區域數據回傳的網路模型，定量研究了區域數據聚合的節能條件，證明了先聚合再回傳比直接進行數據回傳所節省的相對路徑長度，如果大於等於數據相關性與源節點個數的比值時，區域數據聚合一定可以節省能耗，並進一步給出了當數據聚合點在網路的不同位置，或數據的空間相關性不同時，區域數據聚合的節能條件。 -
Geocrp incorporates data fusion into the routing protocol to reduce the amount of information that must be transmitted to the sink node, it also utilizes rotation of cluster - heads to evenly distribute the energy load among the sensors nodes in the network
分層的結構有利於網路的擴展，同時，感知節點發送到簇頭的數據會進行融合，以減少傳輸的數據量，提高節點的能源利用率。
