Energy Harvesting Scheme Using Queuing Theory for Wireless Body Area Network

Abstract

Wireless devices assault the medical field because of its substantial different capacity. The patient point of interest in blinking provisional is to display on overhead exploiting obtainable innovations. Using advanced wireless technologies, this scenario has been conquered. Without being inculcating inside the human body, remote health checking and patients social event data are exploited to assemble quiet curative data that have been done using six typical body sensors. This entire process ensures the versatility. There is no need to visit a doctor or physician persistent intermittently. In this article, we proposed a method to examine the patient health using wireless sensor networks and to analyze the uses of server and tolerance of delay in hospital location of the patient monitoring using wireless body area network (WBAN). The proposed system performance has been compared with an existing system. The proposed system works better than the existing system. WBAN three-tier network architecture is proposed in this paper for data communication for normal and emergency data packets prioritization in communication process. In first tier ZigBee nodes are present; ZigBee radio module generates the packet queues to the Wi-Fi router which acts as a server in the second tier. In third tier, hospitals have the Ethernet which is used to connect the hospital information system. At tier two the M/G/1 and M/G/N priority queuing models are executed. Analyzing the queuing priority, delay and server utilization time was considered by the performance parameters. The M/G/1 and M/G/N priority queuing models were implemented while the crisis patient’s number is more, while using more amount of Wi-Fi routers which recuperates the parameters delay but reduces utilization of the server is recognized. Utilization of the server is more improved using this factor. A bulk data arrival condition with priority queuing used by the delay tolerant of WBAN is proposed.
