The conviction of ??the golden first hour?? and ??the platinum ten minutes?? has been the model professional standard of emergency medical assistance. However, in many countries, the medical services are not up to the standard. A telemedicine system, based on WiMAX wireless technology, is proposed for emergency medical assistance and to implement in the ambulance. The system is specially designed...
Energy management has been one of the hottest issues in recent years. This concern has been raised as significant changes have been noticed in our daily lives. There is a continuous trend that the weather is getting warmer in future years. During summer, the hot and humid weather make air-conditioner a necessity which consumes much energy. These phenomena are regarded as continuous rather than temporary...
A ZigBee energy management system is proposed in this paper. The system is developed based on wireless sensor network technology. The developed system is low cost and robust and fully takes the advantages of ZigBee. Environmental sensors embedded with ZigBee router modules are distributed to different locations to collect the environmental data. With collected data and preset energy quota, the control...
By employing Bayesian neural network, a new QoS prediction algorithm for high speed packet access network has been developed. Network performances are evaluated based on a well developed call admission control scheme, namely the tri-threshold bandwidth reservation scheme. The algorithm helps to improve the resource management, thus saving the cost and bandwidth.
A novel ZigBee Reminder System is proposed as a remedy to the handicaps of current broadcasting systems in airports. The usage, the architecture and the implantation are discussed in details. Network design for the implantation is formulated in this paper. A case study based on the Hong Kong International Airport is presented and findings are given.
A total QoS solution including dynamic call admission control scheme and bandwidth allocation algorithm is proposed for IEEE 802.16e mobile WiMAX. In this paper, the relationship between the channel utilization, the dropping and blocking probability versus traffic loads are investigated. The proposed WiMAX scheme supports voice, data and multimedia services with differentiated QoS.
ZigBee is the latest wireless technology which provides three lowest solutions, low data rate, low power consumption and low cost. One of the ultimate goals of ZigBee is to provide a energy saving solution. Low power consumption and power management are important characteristics of ZigBee. To explore the concept of energy saving, an integrated ZigBee automation system (ZAS) for lighting automation...
