摘要

在無線感測器網路中，其中最重要的研究議題就是在能量有限與不可替換的電池中，所有節點能將能量有效的運用，分群在延長感測器的生命上，是一種受歡迎的方法，近來的工作是在每一回合的群集裡加入一個超級頭來收集各群集的資料並將資料傳送回基地台。依據這個架構，我們在每個群集裡實施更多的角色互換，因此減少在建立群集時在交握中的能量浪費，在一個更實際的能量模型上為基礎，模擬的結果顯示我們提出的架構在可用的感測器數量上有顯著的改善。

One of the most important research issues in wireless sensor networks is the energy efficiency due to the limited energy of the un-replaceable battery in each sensor. Clustering has been a popular approach to extend the life of the sensors. Recent work has added another level of clustering hierarchy by assigning a super head to send back all data collected in each cluster to the base station in each round. Following this approach, we implement more role rotation in each cluster and hence reduce the energy consumed in handshaking for building the clusters. Based on a more practical energy model the simulation results shows that our approach provides significant improvement of sustaining the number of usable sensors.
