Utilising Push and Pull Mechanism in Wireless E-Health Environment
نویسندگان
چکیده
The emerging of wireless computing motivates radical changes of how information is derived. Our paper concerns with developing push and pull based application in wireless environment. We use a simplified e-health (hospital) context to demonstrate some effective uses of pull-based and push-based mechanisms. The pull mechanism involves information retrieval from a database, and update information in the database. The push mechanism is classified into three scenarios, (i) aperiodic push, (ii) periodic push – global recipients and (iii) periodic push – selective recipients.

An examination of the effects of push and pull factors on Iranian national parks: Boujagh National Park, Iran
This article analyses the push and pull factors that bring visitors to the Iranian national parks. The study used a structured questionnaire to collect data on these factors and the socio-demographic profile of the visitors. Survey conducted in Boujagh National Park, an area of 3177 hectares located in the north of the Iran, produced 400 questionnaires. The factor analysis identified four push ...
متن کاملQuerying Dynamic Wireless Sensor Networks with Non-revisiting Random Walks
The simplicity and low-overhead of random walks have made them a popular querying mechanism for Wireless Sensor Networks. However, most of the related work is of theoretical nature and present two important limitations. First, they are mainly based on simple random walks, where at each step, the next hop is selected uniformly at random among neighbors. This mechanism permits analytical tractabi...
متن کاملAdaptive balanced hybrid data delivery for multi-channel data broadcast
With the proliferation of wireless information applications and services, data broadcasting known from radio networks has become an important mechanism for mobile data access in wireless communication networks. Two data delivery techniques, push and pull, and their hybrid combination had been introduced to satisfy mobile user demands. However, most previous research efforts were elaborated upon...
متن کاملMobile Information Systems in a Hospital Organization Setting
The emerging of wireless computing motivates radical changes of how information is obtained. Our paper discusses a practical realisation of an application using push and pull based mechanism in a wireless ad-hoc environment. We use a hospital information system as a case study scenario for our proposed application. The pull mechanism is initiated from doctors as mobile client to retrieve and up...
متن کاملData in Your Space
The wireless world of the future will disseminate data through both push and pull technologies. In this paper, we propose an architecture, which facilitates a global wireless access to data using both push and pull techniques. By combining these techniques on the wireless channels, a more efficient and effective data access paradigm is developed.
