Wireless Sensors Networks based monitoring: Review, challenges and implementation issues

Due to the advances in the field of communications networks there evolved, a very interesting and challenging area of wireless sensors networks, which is rapidly coming of age. These wireless sensors in the network are capable of performing various tasks and sense many types of information for various applications. These wireless sensor network technology has an ample potential to change the way we live and work, as these are applicable in various fields like entertainment, travel, retail, industry, medicine, care of the very young and very old people, emergency management thus enrich lives and make processes easier. In this paper a review of wireless sensors especially designed for health monitoring has been discussed. The characteristics of the sensors for this type of application have been studied. The requirement of the sensor for making a smart sensor network has been investigated. A typical in-house developed system for home monitoring for eldercare application has been presented.
