Wireless Sensor Network: an emerging entrant in Healthcare

Abstract

Today wireless sensor technology holds a remarkable position in each field like healthcare, war and environment. There is a strong need to collect physiological data and sensor networking in healthcare to focus on health-related applications of wireless sensor networks. In this review we introduced some representative applications in the healthcare arena and depict the challenges which innovate to ensure the privacy and security of medical data. The recent enhancements in WSN have given rise to many application areas in healthcare and introduced a new field Wireless Body Area Networks, Which aim to improve different aspects of our lives using vesture and non-vesture sensor devices. Humans can be tracked and monitored, Even if it is with the consent of the person involved but certain social issues arise from this type of application scenario. The issues can be privacy, security, legal and other related issues. In this paper we detail our experiences to explain several prototypes and discuss the driving force behind home health monitoring and focus on how current (and future) technologies will enable automated home health monitoring. A sensor node consist small microprocessor integrated with number of sensors.
