基于IEEE802.15.4的动态自适应占空比方案
A Dynamic Duty Cycle Adaption Scheme Based on IEEE802 . 15 . 4
摘要
Abstract
In wireless sensor networks,IEEE802. 15. 4 MAC adopts fixed(namely,Duty Cycle)scheme. However,network traffic changes dynamically, so the fixed duty cycle is unsuitable for dynamic network traffic. Therefore, this paper proposes a dynamic duty adaption scheme DSBA( Dynamic Superframeorder Beaconorder Adaption) . In this scheme,the duty cycle is dynamically adjusted according to network traffic. Through comparing the number of current data frames with the one of data frames in the next period,two main parameters of duty cycle are dynamically adjusted in order to improve the transmission performance. The simulation results show that DSBA effectively reduces energy consumption,packet loss rate and transmission delay.关键词
