Impact of MAC parameters on the performance of IEEE 802.15.4 MAC protocol with ACK frame transmission

Abstract

IEEE 802.15.4 medium access control (MAC) specifications support an optional feature of MAC-level acknowledgements and frame retransmissions to ensure reliability in data transmission. In this paper, we propose a generalised analytical model, which is based on a three-dimensional, discrete-time Markov chain, to analyse the performance of the IEEE 802.15.4 MAC protocol with retransmission and MAC-level acknowledgements under unsaturated traffic conditions. The network performance is evaluated in terms of aggregate throughput, average power consumption of a node, frame discard ratio and frame delivery ratio. Based on our results, we discuss the impact of different MAC parameters on the performance of the network.

Implementation of the Adaptive CSMA-CA Algorithm Based on Traffic Load

“…Through previous experiments and theoretical analysis, the values of MAC parameters have an impact on the performance of the network [2]. When frames arrive at a moderate rate, devices with a smaller backoff window transmit the frames more quickly and have a higher throughput.…”

“…In the previous work [2], the channel modeled by a discrete-time Markov chain in Fig. 3 has been proposed and we use it for our analysis.…”

“…Markov chains based analytical model are proposed to evaluate the slotted CSMA-CA algorithm in the MAC layer. MAC protocol with ACK frame transmission [2], retransmissions [3] and throughput limit [4] are studied with the above-mentioned models. Bottlenecks of IEEE 802.15.4 are analyzed and different mechanisms are proposed to enhance its performance [5].…”

Analysis of the MAC protocol in low rate wireless personal area networks with bursty ON–OFF traffic

“…For instance, Park et al [6] and Pollin et al [7] presented analytical models for the 802.15.4 MAC based on the bidimensional Markov chain proposed in [14], which has been extensively adopted for modelling the IEEE 802. 11 [7] and Wijetunge et al [16] extended their models to account for unsaturated conditions. Ramachandran et al [8] studied the performance characteristics of 802.15.4 MAC in LR-WPAN under Poisson traffic.…”

“…Therefore, it is important to develop analytical models for 802.15.4 MAC under unsaturated traffic loads. Ling et al , Pollin et al and Wijetunge et al extended their models to account for unsaturated conditions. Ramachandran et al studied the performance characteristics of 802.15.4 MAC in LR‐WPAN under Poisson traffic.…”
