在樹狀網路中根節點進行資料收集時,越上層的節點往往會有越多的資料量,使得傳送資料時有壅塞的現象,我們稱之為瓶頸問題。本論文目標即為解決ZigBee樹狀網路中的瓶頸問題。我們採用IEEE 802.15.4b提出的The Beacon-Only Period Approach來避免beacon訊框的碰撞;同時,我們提出一個集中式的演算法(TDMLF),讓節點能充分利用GTS傳送資料。TDMLF不但避免了IEEE 802.15.4中會發生的隱藏節點問題,也使整個網路達到更有效率的平行化傳輸。模擬結果顯示,我們提出TDMLF能夠有效降低瓶頸問題,因此有較高的資料回傳率。同時,因為不會產生碰撞,TDMLF也減少了因重送資料所造成時間與電力的浪費。
When the root is carrying out data gathering at a tree-base network, the more upper nodes is with more packets usually, we called that bottleneck problem. The goal of this paper is to solve the bottleneck problem at ZigBee tree-bsaed networks. We use The Beacon-Only Period Approach which proposed by IEEE 802.15.4b to avoid the collision caused by beacon frame. Moreover, we proposed a centralize algorithm (TDMLF) that enables the nodes to use the GTS transmission fully. Not only TDMLF has avoided the hidden node problem which occur in IEEE 802.15.4, also enable the entire network to achieve a more effective parallel transmission. The simulation results show that the TDMLF algorithm reduce the bottleneck problem effectively, therefore achieve highly delivery ratio. Moreover, because of no collision, the TDMLF also reduces the waste of time and energy by retransmission.
