A Novel Exception Handling Scheme for Out Patient Workflow in a Wireless Handheld Hospital Environment

چکیده
Thehealthcare services are among the fastest growing service markets deploying wireless technologies. As healthcare organizations continue to become more distributed, mobile handheld devices and their associated support has evolved into a viable platform for these organizations. However, one factor that hinders the deployment of the handheld technology is the lack of support for exception handling over mobile handheld devices in current workflow management systems. In this paper, we propose an extended architecture and scheme for handling the exceptions. Theproposed scheme scans through earlier exception records from a dynamic knowledge base, evaluates and suggests an appropriate solution for the current exception on the mobile handheld device. The scheme is evaluated in terms of time and accuracy compared withpreviously known schemes [6].

متن کاملLPKP: location-based probabilistic key pre-distribution scheme for large-scale wireless sensor networks using graph coloring
Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...

Wireless sensor networks (WSNs) have many applications in the areas of commercial, military and environmental requirements. Regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. A basic approach for preparing a secure wireless communication in WSNs, is to propose an efficient cryptographic key management protocol be...
متن کاملException Handling in Workflow Systems1
In this paper, defeasible workflow is proposed as a framework to support exception handling for workflow management. By using the “justified” ECA rules to capture more contexts in workflow modeling, defeasible workflow uses context dependent reasoning to enhance the exception handling capability of workflow management systems. In particular, this limits possible alternative exception handler ca...

Background and Objectives: Patient discharge process starts from the point of the initial order of the physician order and continues to the discharge time of a patient and the release of the bed that was allocated to him/her. Lengthening the patient discharge process is regarded as a negative factor in the management of beds; this lengthy process leads to delay...
