Abstract

IEEE 802.15.4, Low data Rate low power Wireless Personal Area Network (LR-WPAN) standard uses fixed duty cycle of the superframe operation. Fixed duty cycle operation of the stated standard suffers from several network issues like Personal Area Network (PAN) tedious initialization interval, nodes as

Highlights

  • Real time monitoring in numerous applications like industry, agriculture, academia, entertainment and health care became possible due to sensor networks

  • Slot 0 is used by Personal Area Network (PAN) coordinator for beacon transmission, remaining active part is further divided into contention access period (CAP) and contention free period (CFP)

  • The detailed discussion of all graphs are given in the following subsections: When the Beacon Order (BO) value is set to 2 Body Area Network (BAN) take start abruptly whereas, by setting BO to 8 it takes maximum time to initialize the PAN

Summary

Introduction

Real time monitoring in numerous applications like industry, agriculture, academia, entertainment and health care became possible due to sensor networks. FFD work as a Body Area Network (BAN) coordinator node or personal coordinator, whereas RFDs operate as sensor nodes. These sensor nodes gather physiological data such as ECG, EEG, blood pressure etc. This work focuses on beacon-enable operation of the IEEE 802.15.4 By decreasing parameter’s value results in reducing system bandwidth causing huge energy consumption in response [8] The value of these two parameters is fixed by IEEE 802.15.4 which deliberately restricts nodes movement with respect to its coordinator, causing association loss.
