Performance analysis of IEEE 802.15.6 contention-based MAC protocol

Abstract

IEEE 802.15.6 facilitates communication in the vicinity of or even inside a human body to serve heterogeneous medical, consumer electronics, and entertainment applications. This standard operates in beacon and nonbeacon communication modes, and each mode employs different protocols, including CSMA/CA, for resource allocation on the channel. The CSMA/CA protocol presented in IEEE 802.15.6 allows quick and prioritized access to the channel by differentiating contention window bounds of nodes with different priorities. This paper provides a simple and accurate analytical model to estimate the throughput, energy consumption, and delay of this protocol for different priority classes, under the assumption of a finite number of nodes in saturated and lossy channel conditions. The accuracy of the proposed model is validated by simulations. The results obtained in this paper can be used to design standard priority parameters for medical and non-medical applications Abstract-IEEE 802.15.6 facilitates communication in the vicinity of or even inside a human body to serve heterogeneous medical, consumer electronics, and entertainment applications.

EIMAC: a multi‐channel MAC protocol towards energy efficiency and low interference for WBANs

“…Our multi‐channel EIMAC protocol is developed based on CSMA/CA mechanism, which is a well‐known contention‐based MAC protocol. The analysis framework of contention‐based MAC protocol for single‐channel mechanism has been widely studied in recent years, especially in IEEE 802.15.6 [35]. Therefore, to theoretically analyse the performance of the multi‐channel EIMAC protocol, we refer to [35] and build a comprehensive analysis framework for delay, energy consumption, and throughput.…”

Therefore, to theoretically analyse the performance of the multi-channel EIMAC protocol, we refer to [35] and build a comprehensive analysis framework for delay, energy consumption, and throughput. We assume that the number of available '11' channels is X and the number of available '10' channels is Y in the network.…”

“…The results can easily be extended to other priority levels. Similar scenario settings can be referred to the work in [3,13,16,35]. In the simulation, we analyse the performance of EIMAC protocol with the increasing number of nodes, packet arrival rate, and UP, mainly focusing on the delay, normalised throughput, and energy consumption as shown from Figs.…”

Mobile Wi-Fi based Scheduling for Body Area Networks

“…The scheme reduces delay, packet loss ratio and increase the transmission channel efficiency. In [11], the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol is presented for IEEE 802.15.6 in the beacon communication mode. It allows rapid and prioritized right of entry to the channel by distinguishing CW.…”

CDASA-CSMA/CA: Contention Differentiated Adaptive Slot Allocation CSMA-CA for Heterogeneous Data in Wireless Body Area Networks

“…This is due to limited 16 channels in IEEE 802.15.4 MAC, which is not feasible for N heterogeneous nature of a patient's data.The limitations in CSMA/CA reduces performance of the MAC Superframe structure in terms of a higher data collision. In this way, BMSs re-transmit lost packets, incuring delay, lower data reliability and high energy consumption [13][14][15]. Furthermore, the contention is based on NB (number of backoffs), BE (Backoff Exponential) and CW (Contention Window) as reflected in Equation 1 [16].…”
