Mobile Internet users expect the same network service quality as over a wire. Technologies, protocols, and standards supporting wired and wireless Internet are converging. Mobile devices are resource constrained due to size, power, and memory. The portability making these devices attractive also causes data exposure and network penetration risks. Mobile devices can connect to many different wireless network types, such as cellular networks, personal area networks, wireless local area networks (WLANs), metropolitan area networks (MANs), and wide area networks (satellite-based WANs). Wireless network application examples are e-mailing, Web browsing, m-commerce, electronic payments, synchronization with a desktop computer, network monitoring/management, and reception of video/audio streams.

This paper hypothesises that conditional differential incentives can increase overall participation rates and the proportion of respondents who use a particular device in web surveys. Previous studies have not found effective ways of encouraging participants to use smartphones to complete web surveys. We conducted an experiment using a volunteer online access panel in Russia with 5,474 invitations sent to regular mobile internet users. We varied the invitation mode (SMS vs email) and encouragement to use a particular device for completing the survey: mobile phone or personal computer (PC). SMS increased the proportion of mobile web respondents, while email increased the proportion of PC web respondents. As expected, differential incentives increased the overall participation rates by 8–10 percentage points if higher incentives were offered for completing the survey on a mobile phone. Contrary to expectations, offering higher incentives to PC web respondents did not produce higher participation rates compared to the control condition. Both encouraging the use of a mobile phone and offering higher incentives were effective at increasing the proportion of respondents using mobile devices. In terms of both participation rates and the proportion of respondents using mobile devices, offering incentives 50% higher was as efficient as offering incentives 100% higher for mobile web respondents. Offering higher incentives to mobile web respondents also had an effect on sample composition. Significantly higher participation rates were found among females and those with higher education.

With the emergence of powerful mobile Internet devices such as smartphones, mobile devices are expected to play the role of service providers or even brokers, as well as clients. However, the frequent mobility of devices and the intermittent disconnection of mobile and wireless network may degrade the availability and reliability of services. To resolve these problems, this paper proposes an efficient method for migrating and replicating Web services among mobile devices. Specifically, the proposed method splits the source code of a Web service into subcodes depending on users’ preferences for its constituent operations. For the seamless provisioning of services, a subcode with a higher preference is migrated earlier than others. To evaluate the performance of the proposed method, the effect of the code splitting on migration was analyzed.

AbstractThe library is a source of knowledge and supporting facilities in each educational institution, especially in this discussion the library is at a college or university. With the library, it will facilitate students in finding various information about teaching and learning, and will also improve the teaching and learning process. The Indonesian Internet Service Providers Association (APPJI) in its survey of several years stated that the use of mobile devices has a very large increase. Recorded from 2013 to 2017 has a very large increase of 61.26 million internet users in Indonesia. The behavior of internet users based on the device used to access the internet is 44.16% in the use of mobile devices, mobile devices and computers ortop 4.49%, the use of mobile devices and computers by 39.28%. This means that the behavior of internet users in Indonesia is very dominant in accessing the internet through mobile devices. Moreover statistics show that mobile internet users are also increasing from year to year. Previously there was a library system at the University of Muhammadiyah Malang web-based. But in this case the tendency of the behavior of internet users in the use of mobile devices, the Muhammadiyah University Library of Malang has a huge opportunity in developing an improving services in meeting the needs of students in finding information needs.AbstrakPerpustakaan adalah sumber ilmu pengetahuan dan sarana penunjang pada setiap instansi pendidikan terutama dalam pembahasannya ini perpustakaan yang ada pada perguruan tinggi atau universitas. Dengan adanya perpustakaan maka akan memudahkan mahasiswa dalam mencari berbagai informasi mengenai belajar mengajar, dan juga akan meningkatkan dalam proses belajar mengajar. Asosiasi Penyelenggara Jasa Internet Indonesia (APPJI) pada surveynya dari beberapa tahun ini menyatakan penggunaa pada perangkat mobile memiliki peningkatan yang sangat besar. Tercatat dari tahun 2013 sampai 2017 memiliki peningkatan yang sangat besar yaitu 61,26 juta jiwa pengguna internet di Indonesia. Perilaku pengguna internet berdasarkan perangkat yang digunakan untuk mengakses internet yaitu 44.16% dalam penggunaan perangkat mobile, perangkat mobile dan komputer ataulaptop 4.49 %, pengunaan perangkat mobile dan komputer sebesar 39.28%.  Hal ini berarti perilaku pengguna internet di Inonesia sangat dominan mengakses internet melalui perangkat mobile. Apalagi statistic menunjukkan bahwa pengguna mobile internet juga semakin meningkat dari tahun ketahun. Sebelumnya sudah ada sistem perpustakaan pada Universitas Muhammadiyah Malang berbasis web. Tetapi dalam hal ini kecenderungan perilaku pengguna internet dalam penggunaan perangkat mobile, maka Perpustakaan Universitas Muhammadiyah Malang memiliki peluang yang sangat besar dalam mengembangkan dan meningkatkan pelayanan dalam memenuhi kebutuhan mahasiswa dalam mencari kebutuhan informasi.

And Performance

The latest results in Deep Neural Networks (DNNs) have greatly improved the accuracy and performance of a variety of intelligent applications. However, running such computation-intensive DNN-based applications on resource-constrained mobile devices definitely leads to long latency and huge energy consumption. The traditional way is performing DNNs in the central cloud, but it requires significant amounts of data to be transferred to the cloud over the wireless network and also results in long latency. To solve this problem, offloading partial DNN computation to edge clouds has been proposed, to realize the collaborative execution between mobile devices and edge clouds. In addition, the mobility of mobile devices is easily to cause the computation offloading failure. In this paper, we develop a mobility-included DNN partition offloading algorithm (MDPO) to adapt to user’s mobility. The objective of MDPO is minimizing the total latency of completing a DNN job when the mobile user is moving. The MDPO algorithm is suitable for both DNNs with chain topology and graphic topology. We evaluate the performance of our proposed MDPO compared to local-only execution and edge-only execution, experiments show that MDPO significantly reduces the total latency and improves the performance of DNN, and MDPO can adjust well to different network conditions.

Technical systems in the modern global world are rapidly evolving and improving. In most cases, these are large-scale multi-level systems and one of the problems that arises in the design process of such systems is to determine their reliability. Accordingly, in the paper, a mathematical model based on the Weibull distribution has been developed for determining a computer network reliability. In order to simplify calculating the reliability characteristics, the system is considered to be a hierarchical one, ramified to level 2, with bypass through the level. The developed model allows us to define the following parameters: the probability distribution of the count of working output elements, the availability function of the system, the duration of the system’s stay in each of its working states, and the duration of the system’s stay in the prescribed availability condition. The accuracy of the developed model is high. It can be used to determine the reliability parameters of the large, hierarchical, ramified systems. The research results of modelling a local area computer network are presented. In particular, we obtained the following best option for connecting workstations: 4 of them are connected to the main hub, and the rest (16) are connected to the second level hub, with a time to failure of 4818 h.
