碩士 === 淡江大學 === 資訊工程學系資訊網路與通訊碩士班 === 100 === The advancement of technology changes with each day. In recent years, it extends many different types of wireless network. Wireless sensor networks become a hot issue in research. Wireless sensor networks are composed of multiple sensor nodes that are randomly deployed. Each sensor node has sensing and computing capability to sense different environments according to different applications and transmit these data to sink. However, how to reduce energy consumption in the transmission process is important research. In this thesis, we propose a Tree-based Data Aggregation Mechanism using Center of Gravity (TDCoG). Initially, it builds transmission paths of tree structure, and then does data aggregation. This mechanism may solve the hot spot problem and achieve the effect that loading balancing of energy and extending the lifetime of the network.
