Selective Duty cycle Algorithm for beacon-enabled Low Rate Wireless Personal Area Networks

Abstract

Today in various fields, Low-Rate Wireless Personal Area Network (LR-WPAN) with IEEE 802.15.4 can be utilized for various applications such as Home Automation, Factory Automation, Search & Rescue, Environmental Control, Health Monitoring, etc. In some of the applications, there is no issue of energy consumption; however, there are so many in which energy consumption is a major issue. In fact, performance of the standard should be optimized according to the traffic condition and application. In this paper, performance of IEEE 802.15.4 or Low-Rate WPAN is analyzed with the variation of Superframe Order (SO) or Duty Cycle. On the basis of performance analysis, a Selective Duty cycle Algorithm (SDA) is proposed which can be employed to optimize the performance of the standard according to the packet rate. Through simulations, it is shown that SDA is performing well as compared to other duty cycles.
