在這篇論文中，我們處理的是一個在無線感測網路中的檢測問題。無線感測網路包含一個資料匯集中心與許多的感測器。我們將傳統的檢測問題分成多個階段提出多重階段分散式檢測法，利用每階段所需要不同數目的感測器和每階段不同的門檻來達到節省無線感測網路耗能的效果。
我們考慮每個感測器會將接收到的訊號進行初級的檢測做出一個初級決策，這個初級決策的結果會受到觀測通道的可加性高斯白雜訊影響有可能會產生初級決策的錯誤，每個感測器會根據多重階段分散式檢測法由資料匯集中心通知是否將自己的初級決策經由一個理想通道傳送至資料匯集中心。
我們的目標是希望在我們可接受的檢測錯誤要求之下降低我們的平均傳送次數（平均傳送次數與系統傳輸耗能成正比），為了達到此目的我們必須利用最佳化問題計算出每一個階段所需要的感測器數目和門檻值，我們討論的兩種檢測錯誤要求來去限制提出的方法：檢測錯誤率要求以及假警報機率要求。
在最後的結果我們可以看到在我們提出的多重階段分散式檢測法可以有效的降低系統耗能，尤其是在低訊雜比的情況更是明顯，而即使是在高訊雜比的情況也能維持與傳統方法一樣的耗能，簡而言之，我們提出了一個可行的檢測法來有效的降低無線感測網路中的耗能達到節能的效果。
