關於論文補充說明的部份
針對兩個角度來說明為什麼新模型(扇形分層)較好
1. 傳統型分群法 V.S. 扇形分群法?
以Figure 1來說,紅色傳送路徑為採用傳統型分類法,假設某節點p21到CH再經由p21到BS,
因此此過程之電量消耗可表示為:(pxy)表示第x種分群法之第y步路徑距離
====================================
energy(path2) 與 (p21)*(p21)+(p22)*(p22) 成正比
====================================
而綠色路徑則是採用扇形分層法,此時電量消耗
====================================
energy(path1) 與 (p11)*(p11)+(p12)*(p12) 成正比
====================================
