This paper presents a mobility improvement handover algorithm with less scan time implementation for Mobile WiMAX. Mobile WiMAX is a wireless technology based on IEEE802.16e for broadband wireless access. Mobile WiMAX introduces the most significant new feature, mobility to support for handovers, which can be considered as a basic requirement for mobile communication system. The mandatory hando...

Seamless handover is one of the main goals in Long Term Evolution (LTE). In order to achieve a seamless handover, the handover latency needs to be reduced. By predicting where the users are moving, the resource allocation can perform prior to the actual handover, thus can reduce delays in resource allocation and finally can reduce the handover latency. In LTE femtocells network, the large numbe...

A seamless handover scheme with low latency and low packet loss is an important issue to maintain end-to-end TCP performance of mobile users. Several solutions have been proposed as extensions of Mobile IPv6 to improve the handover performance of mobility, each solution has its own advantages and disadvantages, and therefore, an standardized handover mechanism is not accepted yet. In this paper...

OBJECTIVE To examine the current practice of handover and to record trainees' assessment of handover process. STUDY DESIGN An audit study. PLACE AND DURATION OF STUDY Department of General Surgery, Scarborough General Hospital, Scarborough, United Kingdom, from January to April 2010. METHODOLOGY A paper-based questionnaire containing instruments pertaining to handover guidelines was disse...

Handover is a "major preventable cause of patient harm"[1] and this project aims to improve the quality of night handover within a teaching hospitals general medicine department, resulting in the safe transfer of patient care to the night team. Quality of handover was assessed both qualitatively, via structured qualitative interviews with trainees and a baseline survey assessing doctor's opinio...

Background: Nursing bedside handover has been reported as a method to foster patients’ participation in their care. However, to date, no study has assessed the effect of implementing nursing bedside handover on patients’ perception of being involved in the decision-making process of their care and the side effects of nursing bedside handover. Aim: This study aims to evaluate the effect of nursi...

LEO satellite has an important role in global communication system. They have advantages like low power requirement and lower end-to-end delay, efficient frequency spectrum utilization between satellites and spotbeams over MEO and GEO satellites. So in future they can be used as a replacement of modern terrestrial wireless networks. There are a lot of handover techniques for LEO satellites like...

Next-generation wireless networks should be able to coordinate and integrate different communication systems. It has been a challenging problem to support a seamless handover in these diverse wireless network environments. Link level triggers can provide information about events which can help handover decision and layer 3 entities better streamline their handover related activities. In most co...

Over the years, vertical handover necessity estimation has attracted the interest of numerous researchers. Despite the attractive benefits of integrating different wireless platforms, mobile users are confronted with the issue of detrimental handover. This paper used extensive geometric and probability analysis in modelling the coverage area of a WLAN cell. Thus, presents a realistic and novel ...

In this article we analyze IPv6 handover over wireless LAN. Mobile IPv6 is designed to manage mobile nodes’ movements between wireless IPv6 networks. Nevertheless, the active communications of a mobile node are interrupted until the handover completes. Therefore, several extensions to Mobile IPv6 have been proposed to reduce the handover latency and the number of lost packets. We describe two o...
