Mathematical Analysis of Energy Efficiency in IEEE 802.11 DCF     

高波杨宇航  马惠业 《天津大学学报(英文版)》2005,11(5):332-337

The standardized IEEE ,802. II distributed coordination function （ DCF） provides a contention-based distributed channel access mechanism for mobile stations to share the wireless medium. However, when stations are mobile or portable units, power consumption becomes a primary issue since terminals are usually battery driven. This paper proposes an analytical model that calculates the energy efficiency of both the basic and the RTS/CTS access mechanisms of the IEEE 802. II protocol. The model is validated with simulation results using NS-2 simulation package. The effects of the network size, the average packet length, the initial contention window and maximum backoff stages on the energy efficiency of both access mechanisms are also investigated. Results show that the basic scheme has low energy efficiency at large packet length and large network size, and depends strongly on the number of stations and the backoff procedure parameters. Conversely, the RTS/CTS mechanism provides higher energy efficiency when the network size is large, and is more robust to variations in the backoff procedure parameters.  相似文献

Study on pig growth hormone gene polymorphisms in western meat-type breeds and Chinese local breeds

Chinese Meishan and Jiangquhai pigs are two of the most prolific pigs in the world, but their growth rate is lower than that of Duroc, Landrace and Pietrain pigs. It is suggested that growth rate is regulated by growth hormone. The objective of the current study was to analyze the porcine growth hormone (pGH) gene polymorphisms based on the polymerase chain reaction restriction fragment-length polymorphism method (PCR-RFLP) for three western meat-type breeds (Duroc, Landrace and Pietrain) and two local Chinese pigs (Meishan and Jiangquhai). Five polymorphic restriction sites were detected with the ApaI, MspI, BspI and HhaI restriction enzymes in two amplified fragments (605 bp, -119 to +486; 506 bp, +206 to +711). Breed difference was found only in the 506 bp fragment. There was no difference in allelic frequencies of BspI and HhaI restriction sites among the five breeds (P>0.05). Landrace and Meishan pigs lacked allele G3 of MspI site. The allele G3 frequency of restriction MspI site of the 506 bp fragment in Pietrain pigs was higher than that in Duroc and Jianquhai pigs (P<0.001). For ApaI site, the Meishan pigs lacked allele G1; no difference was found in allelic frequencies among Pietrain, Duroc, Landrace and Jiangquhai pigs (P>0.05). This new and rapid PCR-RFLP typing method is an attractive tool for analysis of porcine growth hormone gene restriction sites. The differences in MspI and ApaI restriction sites may explain the growth difference between the foreign meat-type breeds above mentioned and local Chinese pigs.  相似文献   

民主政治决策的成本与收益分析   总被引：1，自引：0，他引：1  

张爱军  赵波 《信阳师范学院学报(哲学社会科学版)》2005,25(3):1-6

公共选择学派认为政治人的理论预设有助于政治决策领域的分析,如同经济人一样,政治人在政治决策过程中也会不断追求自身利益的最大化。政治收益大于政治成本是政治人的理性预期和根本目标。然而,在民主政治中,政治人的这种预期容易滋生滥用权力的倾向,阻碍民主政治的实现。  相似文献   

不同基因型大豆对硼敏感性的差异   总被引：2，自引：2，他引：2

本文采用田间试验方法研究三种基因型大豆北9395、北454和北384对硼敏感性的差异,结果表明,应试的三个大豆基因型在三个硼处理水平中,其单株粒重均随着硼处理浓度的增加而增加,硼促进籽粒干物质的积累;三个大豆基因型对硼的敏感性存在差异,北9395对低硼最敏感,且高硼时易出现中毒症状;北454需硼范围较宽;北384对低硼不敏感;北454和北384高硼时增产明显.  相似文献   

才子佳人叙述模式在现当代小说中的演变     

杨波 《株洲师范高等专科学校学报》2005,10(1):89-92,104

才子佳人的叙述模式从清末民初开始，经历了一系列的演变，大团圆的结局被打破，叙述对象与情节类型也在各个时期有着不同的面目，直到当代，这种模式真正融入了世俗化的叙述中。成为一道或隐或现的独特风景。  相似文献
