碩士 === 國立成功大學 === 資訊工程學系碩博士班 === 94 === Recent advances in VLSI, microprocessor and wireless communication technologies have enabled the minification of wireless sensor's size and enriched the capability of its computing and communication. These small wireless sensors can sense the environmental phenomenon, process the collecting data, and deliver the data to the basestation by wireless communication. We could deploy thousands of small wireless sensors which sense data actively and communicate with each other over a vast field to construct the wireless sensor network. The common property of the wireless sensor network application is the constant data transmission. Because the energy of a sensor is constrained, we focus on the subject of sensor's energy consumption when developing a data dissemination model to avoid data lost. It is necessary to develop a data dissemination model to make sure the successful data transmission. In this thesis, we develop a low energy consumption and load balance data dissemination model by hand-off. Finally, the performance results show that our alogrithm indeed extend the sensor network lifetime.
