Energy efficient and node selection technique for Wireless Body Sensor Network

Wireless Body Sensor Network (WBSN) is a special purpose Wireless Sensor Network (WSN) which can observe the physiological behavior of the patient or human being. Sensors can collect the data and then send them to the central unit through the Metropolitan Area Network (MAN) or Local Area Network (LAN). Wireless Sensor Network is a collection of several transducers spread across the environment to monitor the various parameters such as blood pressure, heart rate, blood sugar, skin temperature, blood oxygen. The Biomedical Wireless Sensor (BWS) which are attached to the human body is capable of establishing wireless communication link. WBSNs can be known as the distributed system, where nodes are distributed on the human body. In this system, the cluster head node selection technique chooses the best node; the number of nodes is increased between the local nodes, Wireless Local Gateway (WLG) and the Hospital Gateway (HG) for the reliable and efficient communication. By implementing the automatic connection establishment, the time delay in the system can be improved. This method aims to provide instantaneous and remotely accessible monitoring system.
