IEEE 802.15.4 standard is widely adapted for Body Area Sensor Networks (BANs) due to its low duty cycle and low power operation. However, IEEE 802.15.4 recommends the use of fixed duty cycle operation which results in high energy consumption and end-to-end delay. Therefore, an efficient algorithm is needed to adapt duty cycle operation to overcome the end-to-end delay and energy consumption. In this paper, we propose a Joint Duty Cycle algorithm (JDCA) for the BAN to enhance the network lifetime, throughput and decrease the end-to-end delay. Dynamic duty cycle can be adapted by the two MAC parameters: Beacon Order (BO) and Super frame Order (SO). However, these parameters are set by the network administrator before the network deployment. During simulation, JDCA algorithm is capable of adapting dynamic duty cycle at run time based on traffic load. Furthermore, simulation results shows enhanced network lifetime, network throughput and less end-to-end delay when compared with IEEE 802.15.4.
