The ever increasing demand of the subscribers has put pressure on the capacity of wireless networks around the world. To utilize the scare resources, in the present paper we propose an optimal allocation scheme for an integrated wireless/cellular model with handoff priority and handoff guarantee services. The suggested algorithm optimally allocates the resources in each cell and dynamically adj...

BACKGROUND Patient participation in handover is one aspect of patient-centred care, where patients are considered partners in care. Understanding the patient perspective provides a foundation for nurses to tailor their bedside handovers to reflect patients' thoughts and beliefs and encourage their active involvement in decision-making. AIM This study examined patients' perspectives of partici...

: Today, the world is moving very fast because of latest technologies and its innovations. Out of these technologies mobile communication plays an important role in our daily life, since it offers flexibility and mobility. Mobility is the most important feature of a mobile communication system. Success of mobile communication relies on its continuous service provided to the user. Usually, conti...

Few strategies routinely used during shift change handovers in high-reliability organisations (HROs) are used in healthcare. The findings from the paper in this issue by Borowitz et al (see page 6) add to the growing empirical evidence that patient handovers in all healthcare settings are highly variable in content and process. Similar to other highly respected healthcare researchers, the autho...

each handoff scheme, a simple analytical model is developed for the evaluation of two characteristic performance measures: the packet loss probability during handoff and the extra delay experienced by packets that are involved in the handoff. Application of these models allows a comparison of two important handoff schemes: the Multiple Stream Forwarding scheme of HAWAII and the Semi-soft Handof...

In wireless networks, terminating handoff calls is generally more objectionable than blocking new calls. The Guard Channel Scheme (GCS) and Handoff Queueing Scheme (HQS) are the popular and practical strategies to prioritize handoff calls. A key issue when giving handoff calls the higher priority is how to achieve a tradeoff among the handoff call blocking probability, new call blocking probabi...

After review of literature, most of the work is done on handoff between cellular network, i.e. horizontal handoff but, few papers are on handoff between heterogeneous networks are in existence. This type of handoff called as vertical handoff can be simulated. The current problem in handoff makes the system slow and hence increases the latency in the system. In this paper a novel technique based...

This paper studies the soft-handoff mechanism and compares its performance with hard handoff. Our study indicates that although a handset may potentially consume extra radio links in soft handoff, the mechanism provides better opportunity to transfer the link successfully in the handoff procedure. Thus, by carefully planning the overlay areas of cells, soft handoff can outperform hard handoff.

Mobile WiMAX is the technology that guarantee broadband wireless access over long distance. In order to maintain mobility and constant network connectivity in mobile WiMAX, it is necessary to provide handoff. Handoff is an crucial process in wireless networks to promise continuous and effective services. But in Handoff there occurs a problem called Handoff delay. In order to optimize handoff de...
