These articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • Analysis of Handover Interruption in Vertical Handover Procedures based on 3GPP standard   Order a copy of this article
    by Sungjin Shin, Donghyuk Han, Hyoungjun Cho, Jong-Moon Chung 
    Abstract: Applications which required real-time communications like mobile clouds, augmented reality, and Voice over IP (VoIP) have significantly increased, and therefore the need to support seamless connectivity across overlaid heterogeneous networks are becoming more and more important. Handover interruptions (HI) may occur when mobile users move from the long-term evolution (LTE) to wireless local area network (WLAN) (or from WLAN to LTE) during active real-time applications. This paper analyzes vertical handover (VHO) schemes and VHO procedures based on 3GPP for confirming interruption time.
    Keywords: VHO, handover interruption, WLAN, LTE

  • Training in a virtual environment for high risk work at heights   Order a copy of this article
    by Sandra Scott, Jennifer Tichon, Trevor Hine 
    Abstract: Falls from a height are a common reason for workplace fatalities in the construction industry. Such high-risk work is likely to remain inherent in construction tasks requiring further efforts to reduce the risk of falling. As an underlying instability in balance may promote the development of height phobia, the current study investigated the role of fear of heights, and individuals Postural Response (PR) to the perturbation of an elevated work platform while exposed to simulated heights scenarios in Virtual Reality (VR). Postural responses were measured during the VR training experiment and the Acrophobia Questionnaire and Motion Sickness Susceptibility Questionnaire were administered. Results indicated that the height Anxiety (a sub-scale of the Acrophobia Questionnaire) was reduced after the 50-minute VR session comprising 5 trials. Postural response improvement also correlated with decreases in fear of heights. Findings indicate that construction workers may benefit from inclusion of VR exposure to heights as part of preparation to work at heights.

  • Cooperative Transmission Scheme with Single Antenna for Low-Rate Wireless Personal Area Networks   Order a copy of this article
    by Jung-In Baik, Seung-Jun Yu, Sung-Jin Kang, Hyoung-Kyu Song 
    Abstract: Cooperative communications are the useful wireless communication system that gets diversity gain by sharing other antennas. This communication system can be also possible to maintain battery life for long time. Nevertheless, IEEE 802.15.4 which employs cooperative transmission scheme does not have been researched. Thus, IEEE 802.15.4 based cooperative communication system is proposed according to various scenarios. The proposed system can efficiently transmit data and reduce energy consumption. Moreover, the proposed system has an effect on the extension of transmission range by high reliability.

  • An Improved Quasi-OSTBC Scheme for MIMO-OFDM Systems   Order a copy of this article
    by Eui-Hak Lee, Hyun-Woo Jang, Jung-In Baik, Sung-Jin Kang, Hyoung-Kyu Song 
    Abstract: Quasi-orthogonal Space-Time Block Code (Quasi-OSTBC) usingrnthe adaptive constant feedback is proposed to improve BER performance. Thernconventional quasi-OSTBC scheme feeds backs to the fixed antenna usingrnthe estimated channel components. However, it is not efficient in the wirelessrncommunications that has the diverse channel environments. To make the efficientrnsystem, the noise in the receiver has to be minimized and the interference has to berncanceled as the conventional scheme. In this paper, the proposed quasi-OSTBCrnscheme feeds back to an antenna adaptively according to the estimated channelrncomponents. As a result, the BER performance of the system is improved.

  • Design a smart construction work management system for improving the safety and productivity using wearable devices   Order a copy of this article
    by Young-Hwan Choi, Mi-Sun Woo, Seung-Hyun Lee, Min Hong 
    Abstract: The main purpose of this research is to design a smart construction work management system for improving the productivity of construction operations and the workers safety by using wearable smart devices. The proposed smart management system includes the development of smart safety helmets, watches, shoes, and applications to convenientlyaccumulate various construction fielddata in real-time. It can be applied to manage the construction workers productivity and toimprove their safety by providing a warning notification for abnormal situations. Also, it stores the data regarding construction workers safety, physical states, and their construction work progress on to the server effectivelyby using a smartphone.
