When these strategies are able to deliver messages with a high success rate and a low delay in social opportunistic networks (SONs), this however creates unbalanced load distribution, where the most popular nodes carry a much heavier burden compared to others. In this paper, we analyze the efficiency and fairness trade-off of social-rank-based forwarding strategies in SONs. Initially, we investigate the node popularity distribution in real-life SONs. We confirm that the node popularity is power-law distributed, with the existence of a few hub nodes that have many connections with other nodes and therefore are much popular in the entire network. Subsequently, we apply a social-rank-based forwarding algorithm on these human-centric networks. Moreover, we perform two distinct scenarios as follows. In the first scenario, we consider absolute delivery efficiency and examine the impact that hub nodes have on the network delivery performance. We show that these nodes enable the network to deliver messages with a high probability in a low delay; however, this consumes much resources on the central nodes. In the second scenario, in contrast, we consider the absolute fairness of resource allocation across the network nodes. We confirm that maintaining this fairness significantly degrades the network delivery performances.","PeriodicalId":404990,"journal":{"name":"2016 IEEE Asia Pacific Conference on Wireless and Mobile (APWiMob)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127835611","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}

It is an alternative technique of Orthogonal Frequency Division Multiplexing System in wireless communication. Fourier transform and invers Fourier transform of OFDM are exchanged by wavelet transform and inverse wavelet transform. The OWDM Scheme is consists of filter bank decomposition as modulator on transmitter and filter bank reconstruction as demodulator on receiver. The advantages of OWDM system are not only reduces complexity of Fourier Transform on OFDM system but also offers flexibility and optimal resolution. This paper compared two schemes of OWDM system using discrete wavelet transform and packet wavelet transform. The results show that performances of OWDM system based discrete wavelet is better than wavelet packet. However, the sub-band numbers of discrete wavelet cannot be as large as wavelet packets. This is due to the bandwidth divisions on OWDM based discrete wavelet are not same for each level of decomposition and reconstruction process.","PeriodicalId":404990,"journal":{"name":"2016 IEEE Asia Pacific Conference on Wireless and Mobile (APWiMob)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124687660","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}

This learning is enriched by new instructional technologies and online interaction that enables the spectrum of in-classroom through distance learning. Students benefit from the ability to choose the mix of course types that best fits their learning style and availability of time. The primary contribution of this research is identifying the influencing variables of students' intention on adopting webinar technology. The study was conducted by giving a questionnaire to 170 students who expressed in writing their willingness to be respondents and some of the students through deep interview. The reliability of the questionnaire is tested by the Cronbach's Alpha technique, the Validity testing by Pearson Product Moment Correlation technique using SPSS 17. The analysis technique to test the hypothesis based on Partial Least Square Structural Equation Modelling (PLS SEM) by using SmartPLS 2.0. The result shows that the propose model of performance expectancy, effort expectancy, social influence, facilitating condition, attitude toward behavior, content quality and pedagogy have strong predictive power for measuring the students' behavioral intention with R2=61%. Behavioral intention has strong predictive power for measuring the students' use behavior with R2=52%. Following to the results, one of the challenges of distance learning program is the distance between the students and the lecturers. The researcher believes that the distance makes the communication has bigger possibility for any distraction and the engagement between students and lecturer are lesser than in conventional class.","PeriodicalId":404990,"journal":{"name":"2016 IEEE Asia Pacific Conference on Wireless and Mobile (APWiMob)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134345304","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}
