This thesis presents a vertical handover decision (VHD) scheme for optimizing the efficiency of vertical handover processes in the Fourth Generation (4G) heterogeneous wireless networks. The scheme consists of three closely integrated modules: Handover necessity estimation, handover target selection, and handover triggering condition estimation. Handover necessity estimation module determines w...

INTRODUCTION The efficiency of postoperative handover of paediatric patients to the children's intensive care unit (CICU) varies according to institutions, clinical setup and workflow. Reorganisation of handover flow based on findings from observational studies has been shown to improve the efficiency of information transfer. This study aimed to evaluate a new handover process based on recipien...

Handovers from the cardiovascular operating room (CVOR) to the cardiovascular intensive care unit (CVICU) are complex processes involving the transfer of information, equipment and responsibility, at a time when the patient is most vulnerable. This transfer is typically variable in structure, content and execution. This variability can lead to the omission and miscommunication of critical infor...

In heterogeneous networks, network selection by nature is a multidimensional problem. Many parameters need to be considered for handover decision making. Apart from handover accuracy and efficiency, an important consideration is the scalability and signaling overhead of such handover algorithms. In this article we propose to break down a Simple Additive Weighting (SAW) based heterogeneous hando...

INTRODUCTION The aim of the present study was to investigate the challenges faced by physicians during shift handovers in a university hospital that has a high handover sender/recipient ratio. METHODS A multifaceted approach was adopted, comprising recording and analysis of handover information, rating of handover quality, and shadowing of handover recipients. Data was collected at the genera...

3rd generation partnership project (3GPP) Long Term Evolution-Advanced (LTE-A) defines a wireless network standard for high packet transmission rate and low packet latency provisions. When a user equipment (UE) moves away from signal range of serving cell may cause the received signal strength weakened, even if disconnected. To solve this problem, it is necessary to execute handover procedure. ...

In recent years medical handover has been identified as an increasingly important area for hospitals to improve upon, in light of the changes in shift patterns for doctors. Significant changes to weekday handover had recently been successfully introduced at Broomfield hospital. Weekend handover remained a concern, with an electronic and paper system being used simultaneously. Our objectives wer...

Multimedia and video streaming applications are becoming more popular and used by most of the users because of advances in mobile devices and mobile wireless networks. Maintaining continuity of video stream in mobility, handover protocol plays a pivotal role. The important task of handover process is handover prediction and decision. This paper presents a novel approach by considering a traditi...

A transfer of a software system from a party responsible for its development to a party responsible for its maintenance is referred to as software system handover or transition. It does not only include a transfer of a software system or system part, but also a transfer of all the knowledge, experience and responsibilities that are required for managing the system during a software system lifec...

Proxy Mobile IPv6 (PMIPv6) is a networked-based handover protocol for the IP layer, i.e., the layer 3 mobility management protocol. In this work, we integrated fast handover and IEEE 802.21 Media Independent Handover (MIH) Services with PMIPv6 to improve the handover performance over the heterogeneous wireless network environment. Since the handover performance of the predictive mode is better ...
