| Summary: | 碩士 === 國立宜蘭大學 === 電機工程學系碩士班 === 99 === Designing a power-efficient wireless ad hoc network to conserve the limited battery power in exchanging messages has been recognized as one of the important design goals. To achieve this objective, we first employ the concept of Relative Neighborhood Graph (RNG) to obtain a power-efficient logical network topology in which the transmission ranges between nodes are adjusted to the optimal. Then, based on the obtained RNG-based logical network topology, we present a green clustering algorithm to organize the wireless ad hoc network into a power-efficient clustered architecture. Compared to other approaches, simulation results confirm that the clustered architecture organized by the presented approaches can efficiently reduce the energy consumption and, thus, extend the time to live of each wireless node.
