An Energy Consumption Analysis of Beacon Enabled Slotted CSMA/CA IEEE 802.15.4

Abstract

Due to low power consumption and low duty cycle, IEEE 802.15.4 standard is widely used for Low Rate Wireless Personal Area Networks (LR − W P ANs). It works in Beacon Enabled (BEn) and Non Beacon Enabled (NBEn) mode. In BEn mode, it has Contention Access Period (CAP) and an optional Contention Free Period (CFP). During CAP, nodes contend to access the medium for communication while CFP period provides Guaranteed Time Slot (GTS) for low latency and applications requiring specific bandwidth. In this paper, we evaluate the comprehensive energy consumption of slotted CSMA/CA algorithm of IEEE 802.15.4 standard during idle and backoff periods. Simulation results with acknowledgment frame are given at the end of the paper.

Single CCA for IEEE 802.15.4 networks: a cross layer energy model

“…Several works are available in open literature which concerns performance of IEEE 802.15.4 networks [1][2][3]. Basic PHY and MAC layer modelling of beacon-enabled 802.15.4 have been discussed in [4], while the PHY layer error performance is presented in [2]. In [5], the author provides a simulation model for evaluating the performance of slotted CSMA/CA protocol.…”

Adjustment Delay Scheme to Improve Performance IEEE 802.15.4 Networks

“…[25] also presented the analysis correctly for contention access period, but they do not consider about defer transmission if the current superframe is not enough to accommodate transmission. M.B Rasheed at al [26] have proposed an analysis for slotted CSMA/CA for energy consumption, but they only consider about idle condition for the standard and do not propose a new scheme. B-H Lee at al [27] have presented an analytical invorder to improvement performance star networks by using extra carrier sensing for IEEE 802.15.4.…”
