摘要:	近年來由於智慧家庭與智能建築的推動，使得電力線網路系統又重新受到重視。由於電在我們的生活中扮演著重要的角色，使得電力線在我們的生活中無所不在，利用這個早已存在的的網路系統來傳遞訊息，不但能夠省下線路佈建的成本，也大大的降低維護所需的開銷。但是畢竟電力線並不是專門為了資料傳輸而佈建的網路系統，因此電力線網路的通道品質對於資料傳輸而言是一個很大的挑戰。本篇論文設計一套建構網路的流程，將電力線網路的各節點建立成樹狀結構，利用階層式的架構，確保每一個在網路中的結點都可以透過其他節點互通訊息，也實做CSMA/CA 的機制，分散節點的傳送時間，降低資料碰撞的機率，提高網路傳輸的效能。另外針對燈管控制的應用情境，設計了兩個路由方法，以確保所有網路上的結點，都能接收到控制中心所傳送的控制訊息，避免由於電力線網路的訊號衰減或干擾，產生孤點 (isolated node)。In recent years, home automation and intelligent buildings keep growing and become more and more popular, it makes power line communication (PLC) system has been gradually emphasized. Electric plays an important role in our life, so that the power line is ubiquitous around us. Using this pre-existing network to transmit message, may save the building cost for the wires and also reduce the cost to maintain the system. However, power line network system is not especially for data transmission, so the channel quality for data transmission via power line is a big challenge.This thesis design a series procedure for establish the network, the nodes in power line communication network will be built in a tree topology. Using the hierarchical structure network, ensure that each node could communicate with each other. We also implement the CSMA/CA algorithm; spreads the time of nodes attempt to transmit, reduce the probability of collision.We also design two routing schemes for the fluorescent light control scenario; make sure that all of the nodes in the network can receive the message send by control center, avoid the isolated node caused by the interference and the signal attenuation.
