摘要

本研究主要是在多個使用者且多個資料源的無線感測網路中，探討兩大類應用環境的路由策略。這兩大類分別為：(1) 存在某些已建置路徑的情況下，增加一個新的資料源；(2) 在未建置任何傳送路徑的情況下，同時多個使用者要求來自多個資料源的資料。我們依使用者是否要求同質性的資料，針對不同的應用，提出了四個路由策略。在實驗結果中，可以看到所提出的路由策略皆能建置出低耗電量的路徑，且僅使用少量的感測節點去建置路徑。

In wireless sensor networks, we study the issues of routing strategies for the applications of multiple sinks and multiple sources. All applications are classified into: (1) a new source appears while some routing paths are active; (2) no routing path is active, multiple sinks concurrently request the data from multiple sources. We propose four routing strategies for various applications according to the characteristics of users’ queries. The simulation results show the power-efficiency of proposed strategies. And all strategies construct the routing paths only by few sensor nodes.
