本論文是研究行動無線網路(mobile ad hoc networks)中的省電(power saving)機制，省電方法分為電源管理(power management)與電力控制(power control)，文中以電力調整的方法來探討應用在智慧型天線(smart antenna)上的差異，利用多重輸入多重輸出(MIMO)模型作為頻道模擬之形態，藉由數值分析方法比較出智慧型天線的優異性，最後實驗證實本論文之設計構想能使智慧型天線以較少的電量達到更高的頻道(channel)使用率。 In mobile ad hoc networks, power control scheme improved channel utilization that also being avoided the hidden or exposed terminal problem. The method of power control designed in physical layer to transmit, we concern how much power saving rate and channel reuse if smart antenna. In this thesis, we discussed multi-input and multi-output (MIMO) model to simulate the power control scheme. Result of our data analysis, demonstrate that smart antenna can use smaller power than Omni-directional antenna and transmit better in single channel.
