Mobility Management in 5G Heterogeneous Networks: A Handover Scheme for Reducing Handover Failures
… interference. This usually happens when a handover has been delayed. If that happens, then, the handover command message (HCM) will not be received by the UE from its serving BS and, a handover failure (HOF) will be declared. Inter-cell interference is so severe in dense small cells that it …

Investigating seamless handover in VANET systems
… and hence there is a need to explore seamless handover mechanisms. Although VANETs are attracting greater commercial interest, current research has not adequately captured the realworld constraints in Vehicular Ad hoc Network handover techniques. Due to the high velocity of the vehicles and …

Handover in digital cellular mobile communication systems
… include the cell residence time of both new and handover calls, channel holding time and the average number of handovers per call. It is shown that the cell residence time can be described by the generalized gamma distribution, while the channel holding time can be best approximated by the …

Handover Performance in the Mobile WiMAX Netrworks
… In this thesis, an in-depth study of the handover effects of mobile WiMAX networks is carried out. The mobile WiMAX technology is first presented as literature study and then the technologies of handovers for previous generations are introduced in detail. Further, the hard handover of the …

Advanced handover procedure for cellular communication systems
… will result in an increase in the number of handovers, and consequently an increase in the time delays required to perform these handovers. Higher time delays will generate call interruptions and forced terminations, particularly for time sensitive applications like real-time multimedia and …

Enhanced link layer handover based on localization
Wireless Technologies over the past years have become cheaper and more available to users. In the Infrastructure Mode of operation, when a mobile node moves from the coverage of one Access Point (AP) to the coverage of another AP, it is said to undergo handoffs. The mobile node has to complete a …

Factors Influencing Quality of Emergency Department Nurse Shift Handover
Nurse-to-nurse shift handover communication is an essential exchange of information that occurs at shift change with the purpose of ensuring that incoming nurses have necessary information to take responsibility for their patients and to provide high quality, safe care. Poor quality shift handover …

A new framework for minimising handover in multicast mobility
… it introduces the problem of access network handover. Therefore, this is the aim of the research where a new framework will be developed for multicast mobility within WiFi network to reduce and provide smooth mobility when handover occurs. This research is focused on techniques to reduce …

Optimizating and Diffusing a Handover Behavioral Assessment Tool for Simulation
… standardized approach to assessing and trending handover quality across class years could quantify the improvements established through the QEP. This study assesses the utility of the Liang Handover Assessment Tool for Simulation (L-HATS), a valid and reliable behavioral assessment tool tested …

Using Ethnography to Capture Learner Experience in Handover Simulation Modules
BACKGROUND: Patient handovers, frequent, diverse, and integral parts of modern medical practice, involve the transfer of patient responsibility from one team of providers to another.1 This transition of care is often fragmented and has been shown to cause various adverse events, including patient …

TIMING CONTROLLER FOR HUMAN-ROBOT OBJECT HANDOVER: IMPLEMENTATION AND EVALUATION
… compares two controllers for human-robot object handovers. The proposed Timing controller allows users to specify timing parameters for the handover and computes velocity control using Model Predictive Control (MPC). This controller provides feedback if it cannot satisfy those constraints, which …

Bedside handover: structure, process and content - a mixed methods study
Background: The handover (also termed handoff) of patient information and patient care is an essential, albeit risk laden and time consuming activity in clinical nursing practice. Therefore, this nursing practice is both of importance and concern for patient safety and nursing management. The …

Comparison of vertical handover decision-based techniques in heterogeneous networks
… quality of service continuity is termed vertical handover or vertical handoff. Active calls that get dropped, or cases where there is discontinuity of service experienced by mobile users can be attributed to the phenomenon of delayed handover or an outright case of an unsuccessful handover …

Proliferated Low Earth Orbit (pLEO) Satellite Constellation Handover Cost Analysis
In any mobile network, handovers between routing nodes generally cause a reduction in available resources for users. This is very true of proliferated Low Earth orbit (pLEO) satellite constellation networks in which both the satellite and the user are mobile with respect to each other. As …

BIM-enabled recommendations for digital handover process in the highways sector
… projects for improved data management for asset handover. Current literature highlights that there is little research has been done in the highways sector in terms of newly adopted BIM workflows. The role of clients is crucial to lead the projects. They have to understand the adopted process with …

Tribal differences in the post-operative handover: a mixed-methods study
… to patients, so much so that the improvement in handover was listed as one of the top five priorities for the World Health Organisation in 2014. Current handover practices have been evaluated in medicine using numerous techniques on the qualitative – quantitative continuum. The systematic …
