Improved ZigBee Connection Method for Healthcare Device

Generally speaking, bio signal devices for measuring a human bio signal and PDA for collecting bio signals may be personalized in the ubiquitous healthcare system. Therefore, specific bio signal devices connects with the same PDA all the time. And if there are several PDAs in same WPAN region, the bio signal devices may receive beacon messages from multi PDAs and should connect with the exact PDA. We propose the zigbee connection algorithm appropriated to the ubiquitous healthcare system. Simulation results indicate that the scanning time in the proposed algorithm is faster than the Wireless MAC and PHY specifications for LR- WPANs
