  1. Simulations show that using dual cluster head greatly decreases the message overhead for mute discovery and helps in extending the network lifetime

    實驗結果表明使用雙簇首極大地減少了路由發現過程中的信息開銷並且延長了網路的生命周期。
  2. The improvement on selection of cluster head : considering the remaining power and power consumption in transmission of candidate cluster heads, the valve value is adjusted and a new cluster head selection mechanism is adopted

    簇頭選擇演算法的改進:通過考慮候選簇頭節點的剩餘能量水平和它們傳輸時的能量消耗，對leach中的閾值t （ n ）進行調整。從而採用新的簇頭選擇機制。
  3. A new algorithm is proposed that promises to deliver solutions to both the problems mentioned above, by using dual cluster head, which is very useful to minimize the use of epidemic algorithms of any sort, thereby saving a lot of resources and also making mute discovery more easier

    本文提出一種能解決以上兩種問題的新演算法，即在演算法中使用雙簇首，可以減少任何形式的流行演算法的使用，因而節約了許多資源並且使得路由發現更容易。
  4. In the paper, the protocol adopt special route optimize algorithm and tdma time slot assigning algorithm, make node enter low consumption or sleep state in order to reduce the consumption ; aiming at choice the mechanism of cluster head, multi - hop routing and the mechanism of mac, the existing leach protocol is improved

    本文的網路協議是採用特殊的路由優化演算法和tdma時隙分配演算法，使節點進入低功耗或睡眠狀態以降低功耗。協議主要在簇頭的選擇機制、多跳路由、 mac層通信機制等方面，對已有的leach協議進行了改進。
  5. Second, the current routing protocols of wireless sensor network are analyzed, aiming at the disadvantage that the protocols have high power dissipation and short lifetime. based on the leach routing protocol, we improve the leach routing protocol, and then name the advanced routing protocol leach new, in which we improve cluster head selection algorithm and optimal cluster number determination of leach respectively

    並重點對現有的無線傳感器網路路由協議進行了分析研究，針對這些協議存在的整體能耗高、網路生命周期短等缺點，在leach路由協議基礎上，對leach路由協議進行了改進，我們把改進后的路由協議稱為leachnew 。
  6. The innovations of this thesis can be summarized into three points. firstly, the average relative velocity is introducd into a novel adptive weighted clustering algorithm as one important parameter of weight, then it increases the stability and self - adaptability of cluster head. secondly, a new approach to calculating weight is suggested by integrating subjective and objective factors. it is verified by comparison with other approaches to selecting weight. thus the velocity of weight responding to the changes of network topology is increased. finally, using a som neural network to create a classifying model enables every node to learn to identify by itself the role in manet

    本文的創新點有三個:首先本文在wca和aow分簇演算法的基礎上，引入了平均相對移動速度作為權值重要的參數，提出了一種新的基於權值的自適應分簇演算法，提高了簇頭在移動中的穩定性和自適應性;其次，提出了利用主客觀綜合賦權法確定權重的權值計算方法，通過與其他權重選擇方法比較，網路結構變化的權值響應速度得到了改進;最後，論文利用自組織特徵映射神經網路建立分類模型，使得網路中的節點可以自學習地確定簇中角色。
  7. In the leach - new protocol, the mainly improvement of the leach protocol exhibits as follow : for the sake of balancing the network load, the network choose the clusters based on the residual energy ; we take multi - hop communication between sensors instead of single - hop communication, which results in the reduction of energy consumption of clusters ; the new protocol finds the path to the cluster head with the minimum cost, using an algorithm similar to flooding to propagate the cost information and greedy algorithm to find the lowest cost link ; the algorithm for assigning tdma time slot reduces overall delays of network

    在leach - new協議中，對leach協議的改進主要體現在以下幾個方面:根據節點剩餘能量選擇簇頭，以平衡網路負載;節點間採用多跳路由，降低簇頭能量消耗;節點根據能量消耗的代價來選擇至簇頭的路由，通過擴散演算法來廣播代價消息，採用貪婪演算法來選擇能量消耗最小的路徑;採用tdma時隙分配演算法減少網路時延。最後，利用ns2模擬軟體進行驗證。
