To leverage low cost, small size, and low power consumption, Bluetooth 2.4 Gil: radio transceivers can be used as the sensor/actuator communication hardware. To meet the requirements for high reliability, low and predictable delay of data transfer, and support for a high number of sensor/actuators, custom optimized communication protocols may he required for the operation of the base station, as the commercially available solutions such as IEEE 802.15.1/ Bluetooth [46, 47], IEEIE 802.15.4/ ZigBee [48],and IEEE 802.11 [49-51] variants may not fulfill all the requirements.
