Instant Notification System in Heterogeneous Sensor Network with Deployment of XMPP Protocol

There is a need of continuous monitoring of vital parameters of patient at critical situation. The current scenario in hospital has a digital display for such parameters which is observed by nurse. For such monitoring a dedicated person(nurse) is required. But looking at the growing population this ratio of one nurse per patient would be a considerable probable in future. So manually monitoring the patient should be replaced by some other method. Online monitoring has attracted considerable attraction for many years. It includes the applications which are not only limited up to industrial process monitoring and control but has been extended up to civilian application areas like healthcare application, home automation, traffic control etc. This paper discusses the feasibility of Instant Notification System in Heterogeneous Sensor Network with Deployment of XMPP Protocol for medical application. The system aims to provide an environment which enables medical practitioners to distantly monitor various vital parameters of patients. For academic purpose we have limited this system for use of monitoring patients´ body temperature and blood pressure. The proposed system collects data from various heterogeneous sensor networks - for example: patients´ body temperature, and blood pressure - converts it to a standard packet and provides the facility to send it over a network using Extensible Messaging and Presence Protocol (XMPP)-(in more common terms Instant Messaging (IM)). Use of heterogeneous sensor networks (HSN) provides the much required platform independence, while XMPP enables the instant notification.
