A framework for SIP-based wireless medical applications

With advances in wireless networks and portable handheld devices, it becomes natural to use such technologies to improve the effectiveness of health service providers. These technologies enable hospital staff to remain connected to their critical systems regardless of their location in the medical facility. In this paper, we describe how SIP, Zigbee and WLAN technologies are used to support mobility and event management in the medical environment SIP, a signaling protocol, is now adopted as a standard for VoIP. It is also used for presence monitoring, event management, and instant messaging. In conjunction with SIP, WLAN networks are widely deployed in many campuses, enabling mobility. Zigbee is a new standard that can be used for short range, low rate, low power wireless device level communications providing sensing and data acquisition. WLAN and Zigbee proved suitable for deployment in medical premises causing no interferences with medical equipments. In this paper we describe an integrated framework for mobility, presence and event management using SIP, WLAN and Zigbee.
