Simple Wireless Nurse Call on Distance Measurement

Distance Measurement in Wireless Sensor Networks with Low Cost Components

Several ways to estimate the position of a WirelessSensor-Network (WSN) node have been discussed in the past years. Unlike in outdoor solutions where the Global Positioning System (GPS) could be used in most applications, a general solution for indoor usage has not been found. The few existing indoor solutions on the market are highly specialized and rely on infrastructure or on very expensive ...

The Distance Measurement by Using RSSI of Wireless Sensor Network

A self-learning nurse call system

The complexity of continuous care settings has increased due to an ageing population, a dwindling number of caregivers and increasing costs. Electronic healthcare (eHealth) solutions are often introduced to deal with these issues. This technological equipment further increases the complexity of healthcare as the caregivers are responsible for integrating and configuring these solutions to their...

Measurement Distance Effects on Bayliss Difference Patterns

Abstruct-The effects of measurement distance in distorting low sidelobe difference patterns are examined; this is a sequel to a paper on low sidelobe sum pattern effects. Previous calculations have used obsolete suboptimum aperture distributions. The Bayliss linear distribution is a versatile highly efficient and robust optimum distribution; its use here allows a single curve of sidelobe measur...

Adaptive call admission control and resource allocation in multi server wireless/cellular network

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...
