ADCA: Adaptive Duty Cycle Algorithm for Energy Efficient IEEE 802.15.4 Beacon-Enabled Wireless Sensor Networks

Using of wireless sensor networks in extreme and inaccessible environments usually has energy issues of some kind. The IEEE 802.15.4 is designed in general to fulfill this requirement of low data rate ad hoc networks, i.e., a low complex system with ultralow-power consumption. Similar to all IEEE standards, however, IEEE 802.15.4 comes with many flexible variables for optimized local solution such that its beacon-enabled duty cycle mode power management mechanism. Here, we propose a novel adaptive duty cycle algorithm making maximum use of network traffic for automatically adjusting the duty cycle for minimum energy. The system simulation results show superiority of the proposed algorithm for reducing the energy consumption and increasing the throughput for comparative techniques in the literature.
