For the development of the wireless networks the design of seamless and efficient vertical handover is an essential issue. Next generation wireless communications will likely rely on integrated networks consisting of multiple wireless technologies. So the integration of vertical handovers with other wireless technologies, such as WLAN, WiFi, WiMAX, UMTS or 3G, has attracted research community f...

This paper presents two handover mechanisms that can he used in the access part of an ATM-based mobile system. The first handover mechanism, which is called "handover synchronised switching" is relatively simple and does not use any ATM multicasting or resynchrnnisation in the network. It assumes that there is sufficient time available such that all data and history information of the old path ...

This document describes Media-independent Pre-Authentication (MPA), a new handover optimization mechanism that addresses the issues on existing mobility management protocols and mobility optimization mechanisms to support inter-domain handover. MPA is a mobileassisted, secure handover optimization scheme that works over any link layer and with any mobility management protocol, and is most appli...

One of the main issues of Mobile IPv6 is handover latency that causes service disruption time. Although plenty of proposals significantly reduce the service disruption time, they suffer from redundant routing that causes packet misordering and bandwidth consumption during the process of interdomain handover. In this paper, we propose a new scheme that minimizes the redundant routing during the ...

In a heterogeneous network environment, transparent horizontal and vertical handover is a much desired feature. Effective handover solution would allow mobile device users to stay steadily connected, seamlessly switching between different access networks. If it is consistently connected to networks which offers best Quality of Service (QoS) then that would dramatically improve user experience. ...

Activity handover within engineering construction projects is time consuming, takes longer than the actual activities, and therefore, can cause duration delays. This paper presents relay chain seamless handover (RCSH) technology, which is based on relay technology theory and actor-network theory. This study systematically elaborated the RCSH processes, activity relay flows, and methods to addre...

In order to provide a low latency IP handover for real-time mobile and/or pervasive computing service, the IETF has specified FMIPv6 protocol. However, in FMIPv6, if a prediction about a mobile node movement is erroneous, both large handover latency and packet loss result. This is because the handover is performed in reactive mode, when the prediction is found to be incorrect. In this paper, we...

Abstract: The mobile systems are based on cellular approach and the area is covered by cells that overlap each other. In mobile cellular systems the handover is a very important process to maintain the desired Quality of Service (QoS). Many handover algorithms are proposed in the literature. However, to make a better handover and keep the QoS in wireless networks is very difficult. In this pape...

Stream Control Transmission Protocol (SCTP) is a new end-to-end transport protocol that is featured ‘multi-homing.’ The mSCTP (mobile SCTP) is defined as SCTP with the capability of dynamic address reconfiguration. This paper describes a framework of mSCTP handover for supporting vertical handover between heterogeneous IP networks such as WLAN and 3G Cellular systems. We show some experimental ...

Handover performance is an important factor for wireless networks, especially nowadays, when multimedia services are becoming increasingly available over the wireless devices. However, users expect uncompromised mobility when using the service. Thus, the support of multimedia services is not possible if handover is inefficient. At the same time it is clear that a strict separation between IP La...
