Implementations and Evluation of Energy-Aware Routing overS2
No full text早期無線隨意式網路的路由研究，大多專注於單播路由協定(Unicast Routing Protocol)，但隨著網路應用的改變，群播(Multicast)技術的應用層面變廣，重要性也更為增加，因而目前已有諸多針對無線隨意式網路提出的群播路由協定。MAODV(Multicast Ad hoc On-demand Distance Vector)是由國際網路工程研究團隊(IETF)所制定的隨意式群播網路協定，MAODV是採用跳躍數為其路由考量的參數，因此而得到的路由為最短路徑。而，在隨意型無線網路環境中，行動主機通常會受限於網路頻寬、記憶體容量、電能等資源，尤其電能，有不少學者曾提出相關的節能演算法，但如何設計成有效可行的路由協定也是另一種挑戰。本論文修改上述MAODV路由協定，設計一省電考量路由協定 (Energy-Aware MAODV)，達到資料封包傳輸過程中每一條傳輸路徑所消耗的總電量為最小的目標，並且實作模擬在NS-2 2.31版本上。最後進行一連串的模擬來評估並比較原始MADOV和本論文所設計的省電路由協定各種效能上的差異。Most prior works in a wireless ad-hoc network focused on developing an unicast routing protocol. However, recently multicast routing becomes an important issue because the applications using this technique become popular. As a result, several multicast routing protocols in ad hoc networks have been proposed. MAODV (Multicast Ad hoc On-demand Distance Vector) is a multicast routing protocol that was intended for use in mobile ad‐hoc networks by the IETF MANET Working Group. MAODV adopts the number of hops as its routing metric and thus intends to derive shortest‐path routes.n wireless ad-hoc networks, usually, each mobile host has limited bandwidth, memory, and power. Especially power, there have been many existing routing algorithms proposed for this issue, but how to design an efficient and practical routing protocol is a challenge. The purpose of this paper is to revise MAODV’s routing metric and design an Energy-Aware MAODV routing protocol such that the total energy consumption for each path is minimized. The revised MAODV is implemented over NS2 v2.31. A serial of simulations is conducted to evaluated and compare the original MAODV and Energy-Aware MAODV.中文摘要…………i文摘要…………ii謝………………iii錄………………v表目錄…………vii圖目錄…………viii一章 導論…………………………1.1 前言…………………………2.2 研究動機……………………6.3 論文架構……………………8二章 背景知識及研究……………9.1 媒體存取控制層……………10.2 網路層………………………14.2.1 單播路由協定………………15.2.2 群播路由協定………………19.2.3 能量相關之路由協定………28三章 省電路由協定………………32.1 電波傳播模型………………32.2 功率調整的原理……………34.3 省電路由協定之設計………38.3.1 系統架構……………………38.3.2 省電路由協定的表單設計……………39.3.3 省電路由協定的控制封包設計………43.3.4 省電路由協定的運作流程與原理……46.4 實例說明……………………53四章 系統模擬及分析……………68.1 模擬環境設定………………68.2 評估因子……………………73.3 模擬結果與分析……………77.3.1 電量方面……………………77.3.2 封包傳遞率…………………81.3.3 傳送成本……………………81.3.4 平均跳躍數…………………83.3.5 平均端對端延遲時間………87.3.6 網路存活時間………………89.3.7 節點存活率…………………90五章 結論與未來方向……………92考文獻9
Low Input Offset and Common Mode Voltage Amplifier Applied to LLC Synchronous Rectifier Controller
No full text由於各國對於能源轉換效率的要求不斷提高，因此業界為了提高LLC轉換器的轉換效率，而提出同步整流的架構。同步整流是以電晶體開關取代傳統的整流二極體。為了讓電晶體開關能夠模擬出整流二極體的行為，需要同步整流控制器去控制電晶體開關。
但是，由於製程的非理想性，使得應用在同步整流控制器的比較器帶有一個輸入漂移電壓。此輸入漂移電壓會抵消系統送來的訊號量，造成同步整流控制器無法及時地關掉電晶體開關，造成轉換效率降低的問題。在本論文中，提出了一個具有低輸入漂移電壓、低共模電壓的前級放大器，此前級放大器能夠先將系統送來的訊號量放大後，再送給比較器。由於其具有低輸入漂移電壓的特性，所以系統的訊號量不會被抵消，並且由於低輸入共模偏壓的特性，使其能在同步整流的應用環境中正常工作。The requirements of the power converter efficiency are gradually increasing, therefore, the synchronous rectifier had been provided for LLC converter. The basic concept of synchronous rectifier is utilized a transistor switch to replace the traditional rectifying diode and a synchronous controller is required to control the transistor switch to work as a rectifying diode.
Nonetheless, owing to the nonideal phenomena of the manufacture process, the comparator of the synchronous controller suffers an offset voltage which affects the signal from the LLC system. Therefore, the synchronous controller can not be turned off in time and the power conversion efficiency is decreased. In this thesis, a preamplifier with low input offset voltage and low common mode voltage is provided. Due to characteristic of the low input offset voltage, signal from LLC system will not be affected and can be amplified then transferred to the comparator. The characteristic of low common mode voltage ensures the preamplifier works

Material examined. R.V. Fishery Researcher 1, 26°46.11’N, 122°08.70’E, 200 m, 31 Jul 1998, 1 ovig. female cl 2.9 mm (NTOU M02479). Diagnosis. Rostrum extending to distal margin of first segment of antennular peduncle; dorsal margin armed with 4 denticles; ventral margin with 1 denticle; lateral ridge extending posteriorly to base of rostrum. Carapace smooth; rostral basal, hepatic and anterolateral spines absent; antennal spine rudimentary; cervical groove absent. Cornea slightly narrower than eyestalk, darkly pigmented. Third pereiopod with ischium bearing small dorsodistal spine, ventral margin smooth; merus and carpus unarmed; palm with dorsal margin slightly serrated while ventral margin distinctly serrated; tips of fingers strongly curved; cutting edge of dactylus with1 stout tooth near midlength interlocking with similar-sized tooth at midlength of fixed finger. Pleon glabrous; first to fifth pleura unarmed. Sixth pleonite widened posteriorly, unarmed on ventral and posterior margins. Telson with 2 dorsal longitudinal ridges each bearing 2 spines; additional 2 pairs of spinules present near base. Uropods with endopod and exopod serrated on lateral margins. Coloration. Not known. Distribution. Western Pacific: Japan, East China Sea, Indonesia, New Caledonia, Loyalty Islands, Wallis and Futuna Islands, Tonga and now Taiwan, at depths of 200– 480 m. Remarks. The single Taiwanese specimen collected has the rostrum slightly broken distally. Spongicola levigatus closely resembles S. teres Komai, 2015 from French Polynesia (Komai 2015). These two species can be distinguished by the lateral rostral ridge being restricted to the rostrum in S. levigatus but extending to the anterior part of the gastric region in S. teres. In addition, the grooming apparatus of the first pereiopod is well developed in S. teres but rudimentary in S. levigatus (see Komai 2015). The present species is also similar to S. liosomatus Rodríguez Quintal & Goy 2019 from Venezuela in having reduced armature on the body and appendages (Rodríguez Quintal & Goy 2019). The ventral margin of the third pereiopod chela, however, is serrated in S. levigatus but smooth in S. liosomatus (Rodríguez Quintal & Goy 2019).Published as part of Chen, Chien-Lin & Chan, Tin-Yam, 2022, New records of spongicolid shrimps (Crustacea, Decapoda, Stenopodidea) from Taiwan, pp. 255-266 in Zootaxa 5189 (1) on page 261, DOI: 10.11646/zootaxa.5189.1.23, http://zenodo.org/record/711956
