Wireless sensor network is widespread used in hospital environment with mobile device such as NFC, RFID tag and small sensor nodes. The use of a mobile agent in healthcare system under wireless network environment gives an opportunity to offer better services for patients and staffs such as doctors and nurses because of its mobility. But, optimized security protocols and schemes between sensor and patient device are essential for high performance and security problem in U-healthcare system. But a lot of threats, attacks and vulnerability are induced because of limited resources such as small memory and low computation capability in wireless sensor network. The characteristics of U-healthcare systems are analyzed to solve security issues in this paper.
