Polling in the frequency domain: a new MAC protocol for industrial wireless network for factory automation

Abstract

Wireless technologies are becoming more and more attractive for industrial communication. In the field of factory automation, the high communication requirements in terms of predictability, reliability and real-time make the adoption of wireless technologies challenging, due to the inefficiency of the wireless physical layer and deterministic medium access control (MAC) protocols. In this paper, a frequency domain polling MAC protocol (FDP-MAC) is proposed, which takes advantage of the orthogonal frequency-division multiplexing (OFDM) technology to achieve simultaneously polling. In the FDP-MAC, a dynamic time division multiple access (TDMA) scheduling and a downlink acknowledgements aggregation method are also presented to improve the communication efficiency further. We validate the effectiveness of FDP-MAC through simulations, and results indicate that FDP-MAC can meet typical factory automation applications' communication requirements.

Performance Analysis of the Industrial Wireless Networks Standard: WIA-PA

“…The paper [17] studies a collisionfree multichannel superframe scheduling problem for WIA-PA. The paper [18] presents a frequency domain polling MAC protocol for WIA-PA. The paper [19] studies random time source protocol for WIA-PA.…”

“…On the other hand, wireless technologies suffer from the harsh industrial environments since wireless channels are extremely prone to severe damage due to the coexisting interference, fading, and multi-path effect [5,7]. Therefore, guaranteeing the deterministic requirement on the industrial wireless network in spite of the unfriendly wireless channel turns out to be a challenging problem, and industrial wireless networks (IWNs) have aroused a great deal of interest from academia [8][9][10][11][12][13][14][15][16][17][18][19][20][21], industry [22][23][24] as well as standardized organizations [25][26][27]. This paper aims to study IWNs from the standpoint of IWNs standards.…”

Asynchronous multi-channel neighbour discovery for energy optimisation in wireless sensor networks

“…In recent years, industrial automation makes great progress in many aspects, and therefore, there is a great demand for industrial wireless sensor networks (Lin et al, 2014;Wang et al, 2013;Meng et al, 2010;Liang et al, 2011). Industrial wireless sensor networks must not only be designed to handle the reliability and timeliness, but also need to extend the lifetime given the condition of the battery supply or other non-continuous power (Xiao, 2005;Xiao et al, 2004;Chen et al, 2006;Wang and Xiao, 2006;Wu et al, 2005).…”
