Wireless communication devices have become necessary because mobile devices such as smartphones enable people to retrieve data anywhere. Such a high level of convenience is accessible when quality of service is excellent, particularly when wireless network traffic is light. However, for several reasons the actual network traffic will be really heavy. Therefore, designing a mechanism that improves the efficiency of queue management is crucial for enhancing quality of service. This paper proposes a mechanism for queue management in IEEE 802.11e enhanced distributed channel access (EDCA). When a queue has no space for allocating packets, overflow occurs. By designing Tail Drop, the packets that have recently arrived (i.e., the overflow) are discarded until a queue has sufficient room for allocation. According to the EDCA protocol, the transmission opportunity (TXOP) is the finite time during which a machine may send packets. Queue management systems record information regarding successful transmissions. Based on previously collected information, the proposed queue management system decides whether the packets to be assigned to the corresponding transmission queue or not, according to the number of retransmissions. Our experiment results show that this system can efficiently reduce the average number of the discarded packets by 11.6% for video streaming.","PeriodicalId":152001,"journal":{"name":"2015 International Symposium on Next-Generation Electronics (ISNE)","volume":"95 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115758335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, Cu was found capable to be directly electroplated on CoW layers. As a result, a single layer of CoW alloy which demonstrates electroplating, wetting and barrier ability simultaneously could become a promising material for next-generation Cu metallization.","PeriodicalId":152001,"journal":{"name":"2015 International Symposium on Next-Generation Electronics (ISNE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115159481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preparation of the glass systems were realized by melting the mixture of TeO2 and ZnCl2 chemicals in a platinum crucible at 850°C for 60 min in air. In the experiments, thermal analysis was performed to determine the thermal characteristics such as, glass transition (Tg), crystallization (Tp), and melting (Tm) temperatures for different heating rates (B=10, 20, 30 and 40 °C/min) by using the differential thermal analysis (DTA) plot. By considering the DTA plots, the crystallization activation energies were determined by using the Ozawa and modified Kissinger equations. Finally, thermal analysis show that the crystallization activation energies were 487.6kJ/mol, 215.8kJ/mol, 392.kJ/mol, and 273.3kJ/mol for the x=10, 20, 30, and 40mol% ZnCl2 contents, respectively.
