The semi-soft handoff scheme for Cellular IP is optimized for networks where the mobile host is able to listen/transmit to two or more base stations simultaneously for a short durationthe time that the mobile host spends in the overlap areaas in the case of a WaveLAN or Code Division Multiple Access (CDMA) network. This scheme improves the network efficiency off handoff in terms of packet loss ...

It is well–known that TCP often experiences severe performance degradation in mobile networks since due to host mobility, packet losses not related to network congestion occur frequently. In this paper, we propose a buffering of packets at a base station to resolve such a problem. Our method can be used without sacrificing the scalability in Mobile IP based networks. For this purpose, we first ...

In the mobile IP-enabled wireless LAN (WLAN), packet transfer is interrupted due to the handoff of a mobile node at the link and network layers, which results in burst packet loss. This transient behavior is hurting time-critical streaming media applications. Many ideas mitigating the interruption have been suggested such as reducing handoff latency and minimizing packet losses. Also, in the ap...

Femtocells are low power base stations that provide better radio coverage to portable users through femtocell access point (FAP) at the indoor scenario. The access node named as FAP, perform as the base station (BS) for the femtocell and take help of internet as backhaul to get connected with MBS. In these emerging dual layer networks, handoff facilitates for a mobile user moving from a network...

OBJECTIVE To assess how the quality of communication is perceived during patient handoff in areas of intensive care. MATERIALS AND METHODS Cross-sectional study conducted at a university hospital. The study assessed the perception of the quality of information received during patient handoff and the chance of physicians working on-call shifts in intensive care areas mistaking the information ...

In future personal communications networks (PCN’s) supporting network-wide handoffs, new and handoff requests will compete for connection resources in both the mobile and backbone networks. Forced call terminations due to handoff call blocking are generally more objectionable than new call blocking. The previously proposed guard channel scheme for radio channel allocation in cellular networks r...

A multi-level dynamic guard channels (MLDGC) scheme to efficiently provide priority access for handoff calls over new calls in cellular systems is proposed. The switch between levels is controlled by the number of dropped calls. Each additional level has an increasing number of guard channels as triggered by the number of dropped calls. An analytical formulation of the steady state probabilitie...

In this paper we describe the design, implementation and evaluation of a programmable architecture for profiling, composing and deploying handoff services. We argue that future wireless access networks should be built on a foundation of open programmable networking allowing for the dynamic deployment and management of new mobile and wireless services. Customizing handoff control and mobility ma...

In this paper, an efficient neighbor AR (Access Router) discovery scheme and handoff procedure using neighbor information are proposed. It allows each AR and Mobility Anchor Point (MAP) to know neighboring ARs and MAPs, and therefore, a mobile node (MN) can perform the handoff process in advance, using the proposed handoff mechanism. It is important to note that the Inter-MAP domain handoff imp...

Abstract — The demand for wireless mobile networks led to an increase in handoff calls. Optimum utilization of the channel should be planned as it is the limited resource for any mobile network. Poorly designed handoff schemes lead to a drastic decrease in quality of service. The study gives an analytical framework of handoff procedure when some channels are purely reserved for handoff calls. I...
