室內室外環境異質網路優化軟體平台之開發

近年來無線通訊網路日漸普及，系統業者在規劃網路時，如何與既有的系統做結合並建構出效能更好的通訊網路是一個很重要的議題，為了讓網路佈建者在規劃時能有一些有效的參考依據，同時節省成本，減少直覺判斷的不周全，吾人將建構一套異質網路優化的軟體平台，期望規劃出更好的無線通訊網路系統，提供更多有用的資訊。在本論文中，吾人延續實驗室已開發之室內網路軟體平台，將其進一步發展至兼具室內室外環境且異質網路考量的模式，提供使用者更多有用的資訊，例如：行動端所接收的信號場強、訊號干擾雜訊比(Signal to Interference and Noise Ratio, SINR)、資訊流通量(Throughput)等等。在基站規劃方面，為了更符合實際需要，吾人考慮在既有的基站存在時，佈建全球微波互通擷取技術(Worldwide Interoperability for Microwave Access, WiMAX)之基站時的優化，以提供整個環境更均勻且更高之Throughput分佈。吾人利用基因演算法(Genetic Algorithms, GA)去配置基站的位置，之後再進一步去做異質網路共存時WiMAX基站佈建的優化，其中考慮的參數包括基站種類與數量、Throughput、SINR等等。在路徑模擬方面，當異質網路之基站已佈建完成時，吾人以使用者的角度去做規劃，在不同的模擬路徑底下，提供相關的Throughput資訊及效能較好的系統讓使用者做選擇。本軟體能提供使用者詳細之接收場強、SINR、Throughput等資訊，並藉由系統優化之功能，提供整個環境更均勻且更高之Throughput分佈，建構出效能更好的無線通訊網路系統。

The wireless communication networks have already been popularized in recent years. It is an important issue that how to combine the new system with the existing one and construct a better wireless communication network when the network operators plan a new network. In this thesis, a heterogeneous network performance enhancement software platform was built in order to reduce the cost and provide more useful reference resources for the network planners instead of imperfect traditional judgment by experience when planning a network. Then a better wireless communication system was achieved and the user can get more useful information. In this thesis, the indoor network software platform built by lab was continued to be further developed the mode including indoor and outdoor environments in the heterogeneous network and then the software can provide the users more useful information, for example, the received signal power level, SINR and throughput in mobile terminals, etc. In the aspect of cell planning, in order to match the actual need, the cell planning optimization for WiMAX system was considered when some base stations existed in the initial state. The genetic algorithms were used to deploy the locations of base stations and further optimized the cell planning for WiMAX in the coexistence of heterogeneous networks and then provided the whole environment with uniform and higher throughput distribution. In the optimal process, some paramaters like the base station types and numbers, throughput, SINR, etc, were taken into consideration. In the aspect of route simulation, the route simulation optimization was planned in the point of view for the user when the heterogeneous network base stations has been deployed completely. The software platform will provide relevant throughput information and network with better performances for user to choose. The software can provide user the detail received signal power level, SINR and throughput information. The cell planning optimization tool can provide the whole environment with uniform and higher throughput distribution and finally achieved a wireless communication system with better performance.
