Life Time improvement in sensors using Blue tooth node

Abstract

In this paper a  Blue tooth node Topology is proposed for wireless body area sensor networks for the transmission of Electrocardiogram Signals from heart, where the continuous monitoring of patient is required without human. This topology  is very much beneficial in this scenario for data integration. The parameters that has been used are less, so this topology used less number of nodes.  That signal should be required to continuously monitored in many medical situations, whereas in some situations, continuous monitoring is not an essential requirement, this topological scheme played an important role in the designing of link for WBASNs. In case of biological sensor network, it’s very important that implanted nodes consume less power in transmission because the replacement of nodes is very complex surgical procedure in many medical situations the patient is on high risk. A node role change concept is introduced here. The main aspect of this paper is to present topology that provides fast and accurate transmission of biological signals with least used power.  In this the smart sensor nodes topology is utilized these nodes incorporated with sensing and transformation capability. The node sense the biological signals and these signals are  transferred from source to destination by using different relays. The life time of  the module in side the human heart is improved by its correlation(Friendship)with the node out-side the human body.  In that manner the fast transmission of Electrocardiogram data with life time improvement of implanted node becomes possible on low data rate sensor network link.
