Abstract

Energy consumption is one of the most fundamental constraints in wireless sensor network (WSN) design. While data transmission is usually the most energy consuming event, minimizing the transmit power under the condition of satisfying the required packet transmission quality would be an important and effective strategy for reducing energy consumption. In this paper, a novel Adaptive Transmit Power Adjustment technique (ATPA) for ZigBee network under Wi-Fi interference is proposed and implemented in the Crossbow MICAz motes of our testbed. The proposed ATPA technique dynamically and rapidly adapts to the varying interference from the collocated wireless local area network (WLAN) and selects optimal transmit power level that not only decreases the energy consumption of packet transmissions, but also maintains the required packet loss rate (PLR). The effectiveness of ATPA has been validated through the comprehensive performance evaluation experiments conducted on our testbed.
