“…Many physiological monitoring systems for home tele-healthcare and pervasive healthcare applications had been widely investigated. This includes ECG monitoring and transmission using cable television (CATV) network (Lee et al, 2000) or over the Internet (Herná ndez et al, 2001), personal health monitoring by wearable or portable devices (Anliker et al, 2004;Kang et al, 2006;Lee et al, 2006Lee et al, , 2007Leijdekkers et al, 2007;Lin et al, 2004;Lorincz et al, 2004;Milenković et al, 2006) or by clothing-embedded transducers (Axisa et al, 2005;Coosemans et al, 2006), and wireless physiological monitoring systems based on existing mobile communication technologies such as wireless application protocol (WAP) (Hung and Zhang, 2003;Maglaveras et al, 2002), wireless local area network (WLAN) (Cypher et al, 2006;Leijdekkers et al, 2007;Lin et al, 2004;Milenković et al, 2006;Varshney, 2006Varshney, , 2007, and global system for mobile communications (GSM)/ general packet radio service (GPRS) (Lee et al, 2006(Lee et al, , 2007, or over emerging ad hoc wireless networks or sensor networks (Lorincz et al, 2004;Milenković et al, 2006;Stankovic et al, 2005;Varshney, 2007;Varshney and Sneha, 2006). From these literature data, there is a general tendency for healthcare monitoring systems to integrate wireless mobile communication network technology to provide more freedom, portability, and convenience to elders and patients, especially in applications for indoor environment such as homes and hospitals.…”
