Abstract :
The WiseNET system includes an ultra low-power system-on-chip (SoC) hardware platform and WiseMAC, a low power medium access control protocol (MAC) dedicated to duty-cycled radios. Both elements have been designed to meet the specific requirements of wireless sensor networks and are particularly well suited to ad-hoc and hybrid networks. The WiseNET radio offers dual-band operation (434-MHz and 868-MHz) and runs from a single 1.5-V battery. It consumes only 2.5-mW in receive mode with a sensitivity smaller than -108-dBm at a BER of 10-3 and for a 100-kb/s data rate. In addition to this low-power radio, the WiseNET system-on-chip (SoC) also includes all the functions required for data acquisition, processing and storage of the information provided by the sensors. Ultra-low power consumption with the WiseNET system is achieved thanks to the combination of the low power consumption of the transceiver and the high energy efficiency of the WiseMAC protocol. The WiseNET solution consumes more than 250 times less power than comparable solutions based on the IEEE 802.15.4 standard
