dc.description.abstract | 在無線感測器網路裡,Zigbee協定是使用最普遍的一種,它建構於IEEE 802.15.4 協定之上,是專門針對低功率、低傳輸速率、短距離的無線個人網路所設計的。在此篇論文中,將對於Zigbee中省電機制作進一步的改進,致使在許多應用上能更節省電力。
在Zigbee 協定中,三種型態的device : coordinator、router、end-device中,唯讀end-device可以進入睡眠機制,對router而言,雖然扮演著傳遞資料的中繼點,但是當它不被需要時,無線電功能仍然呈現開啟狀態,因此會消耗多餘的電力,在此論文中,將針對router睡眠機制的加入作研究,使router 在不被只用的狀況下,有一定的機會把無線電的功能關掉以節省電力。 在整篇研究機制中,分成路徑建立以及睡眠機制的判斷。路徑建立部分是對於AODV 演算法作一些改良,以幫助整個睡眠機制判斷的完整性,而每一個router進入睡眠模式前,都須經過判斷允許方可進入,而睡眠機制的判斷宗旨,是確保資料傳遞時的順利送達,鄰近的節點需維持一條以上的路徑可達目的地。本篇論文將使用模擬軟體,在Zigbee協定中加入睡眠判斷機制,呈現router可睡眠的網路模型。 | zh_TW |
dc.description.abstract | Zigbee protocol is the most famous protocol using in wireless sensor networks (WSNs), and it is constructed based on IEEE 802.15.4, which is designed specifically for low-rate, low-powered, and short-distanced wireless personal area networks. In this paper, the power consumption in Zigbee is focused and the mechanism is helpful to save the power in some applications.
In Zigbee, there are three kinds of devices : coordinators, routers, end-devices. There is only end-device that is available with low power mode. Sometimes routers are idly hearing the air without relaying messages, and then they consumed more energy. In this research, routers are designed to have low power modes with some sleeping mechanisms. The research are divided into two parts: enhanced AODV routing method and low power mode mechanism. Each router plan to enter low power mode should follow the main rule that no node will be isolated. Once it is accessed to sleep, the power would be saved more than active mode. | en |
