Analysis and Improvement in Tracking & Security of Wireless Body Sensor Network with the help of Quantum Cryptography: - A Retrospective View on Literature Survey
The wireless nature of the network and the wide variety of sensors offer numerous new, practical and innovative applications to improve health care and the Quality of Life. Using a WBSN, the patient experiences a greater physical mobility and is no longer compelled to stay in the hospital. In this paper, we also present an idea to improve healthcare systems in India with the help of telecommunication and information technology by using wearable and implantable body sensor nodes which does not affect the mobility of the patients with extra security and advance feature. A WBSN should ensure the accurate sensing, tracking of the signal from the body, carry out low-level processing of the sensor signal and wirelessly transmit the processed signal to a local processing unit. In the proposed system, WBSNs, a sparse network of sensors are deployed either directly on the human body, inside the body or embedded in everyday clothes, to record and transmit health data. Body Sensors record and transmit data to a Body Central Unit which aggregates data sent by all Body Sensors and relays the aggregation to a hospital monitoring station from where healthcare professionals can remotely monitor the health parameters of patients or other individuals. This will help the authorized care giver easily diagnose the problem and make available the quick treatment to patient. The security of these devices is very important factor to make secure the personal data of any patient. Thus no other unauthorized person can get information about the patient disease etc which help to protect privacy of user and data. The primary objective of this proposed work is to propose effective security and tracking technique for sensor body wireless network with the help of new and effective technique Quantum Cryptography which provides extra security from all type of dangerous attacks and threats
