IEEE802.15.4 wireless sensor networks are increasingly used in building energy management. Due to the wireless nature of these networks, protocols need to be energy efficient, energy harvesting, and self-organizing. The IEEE802.15.4 standard does not provide any functions to allow adaptation of protocol parameters for optimal power efficiency. We present an energy aware communication framework for IEEE802.15.4 wireless sensor networks comprising of algorithms that self-configure protocol parameters during run-time for minimum power consumption while fulfilling building monitoring and control application requirements.
