- Abstract
IEEE802.15.4 is a standard proposed to support physical and MAC layers for low power, low data rate and low cost Wireless Sensor Network (WSN) applications. ZigBee standard supports upper layers. The goals of ZigBee standard are compatible with that of IEEE802.15.4, hence, both standards names are accompanied in one expression, that is, the IEEE802.15.4/ZigBee standard. Beacon Order (BO) and Superframe Order (SO) are the main factors that affects the beacon frame performance. Those two parameters determine node's active and inactive periods and through which the node duty cycle is estimated. BO and SO values must be chosen carefully when the standard MAC is parameterized since some combinations prevent the overall network operation while others may degrade standard performance dramatically. Finding optimal combination of (BO, SO) is related to the applications specific behaviors and is affected mainly by the applications arrival rates of data. This work studies the standard beacon enabled mode behavior through deep mathematical analysis and intensive simulation. Furthermore, it proposes a model that comprises of two adaptive schemes and from which an improved hybrid adaptive technique called Adaptive Duty Cycle (ADC) is proposed. ADC algorithm converges to the network current performance and reduces the standard consumed energy accordingly while improving other performance metrics such as throughput and average delay irrespective of the duty cycle. Performance of ADC is compared to the original MAC algorithm using QualNet 5.2 simulator. ADC reduces energy consumption by 24% and decreases average delay up to 51% while it increases throughput by 56%, thus, the new hybrid adaptive algorithm ADC is proved to outperform the original MAC algorithm.
