| Summary: | 碩士 === 國立臺南大學 === 數位學習科技學系碩士班 === 96 === Wireless Sensor Networks (WSNs) are characterized by low bandwidth, limited energy, and largely distributed deployment. The lifetime of system depend on sensor nodes'' limited energy in the WSNs. Thus, efficiently routing data to reduce energy consumption is a critical issue in the WSNs.
In this thesis, we proposed a guided data aggregation protocol to resolve the problem of efficiently routing data. We use the method of giving each sensor node a appropriate value of node weight, WSNs could build a efficiently routing path automatically. In the WSNs, an event was detected by several sensor nodes. For reducing the transmission of duplicate data, we propose the virtual grid for aggregate duplicate data to reducing the transmission of redundant data. The simulation results show that our proposed guided data aggregation protocol could routing data efficiently and reducing the energy consumption.
