| Summary: | 碩士 === 國立臺灣大學 === 資訊工程學研究所 === 93 === Data Dissemination to mobile sinks within wireless sensor networks is a difficult problem due to limited resources of sensors, such as energy, storage capacity, and computing capability. Although flooding the location information of mobile sinks seems to be a naive solution to sink mobility, it drains the sensors of their
battery power rapidly. Thus, we propose a hierarchical
cluster-based approach, named HCDD, to disseminate data to the mobile sink with light overhead. In addition, unlike other works, our approach operates without location information of nodes, that is, it does not need any expensive and power-consuming GPS devices. Finally, we will show that HCDD has better data delivery, longer network lifetime, and lower overhead compared with
TTDD-like methods in simulation results.
