“…Additional information and a detail analysis of the registration and emergency stop state may be found in [7]. In contrast to [7], which analyses all states of the ALL MAC, this paper investigates the impact of retransmission slots in the standard operation state. Once the registration is completed successfully, the network switches to the standard operation state.…”

“…Since the unsuitability of this amendment to entirely fulfill the high requirements of factory automation has been revealed by the work of [6], an improved MAC is presented in this paper. In contrast to [7], which investigated all states of the ALL MAC, this paper presents and analyzes the extension of retransmission timeslots in the standard operation state. The latency of WSNs based on the IEEE 802.15.4 IR-UWB compliant PHY and the optimized MAC are investigated focusing on the impact of retransmission timeslots.…”

Communication in industrial applications like wireless factory automation demands high reliability and low latency. Due to the fact that state of the art wireless sensor networks do not entirely fulfill the high requirements, new approaches have to be developed. An ultra-wideband system in combination with a MAC protocol for time-critical applications seems to be a promising approach. This paper introduces an optimized MAC protocol to guarantee the stringent real-time requirements of factory automation. Based on a realistic network scenario and IEEE 802.15.4 impulse-radio ultra-wideband physical layer simulations, both reliability and latency are examined. Moreover, the impact of retransmissions is analyzed. The proposed MAC protocol minimizes the resulting latency meeting entirely the requirements of factory automation.

“…Based on IEEE 802.15.4, lots of protocols have been proposed so far to accommodate the requirement of each node to perform real-time computations and to send high-quality data with guaranteed QoS [13][14][15][16][17][18]. In this chapter, which is based on our previous work [19], we present an overview on some interesting mechanisms used in existing adaptive and real-time protocols based on IEEE 802.15.4.…”

WSANs provide the infrastructure for many applications of CPS. Lots of these applications use the IEEE 802.15.4 standard. However, it does not provide any means of differentiated services to improve QoS for time-critical and delay-sensitive events. A large amount of efforts have been made to address such issues. In this chapter, an overview on some interesting mechanisms used in existing adaptive and real-time protocols in compliance with IEEE 802.15.4 is presented. Careful examination of these research works reveals that by optimizing the original specifications and dynamically adjusting the protocol parameters, the total network efficiency can be significantly improved. Nevertheless, there are still certain challenges to overcome in pursuing the most appropriate protocol without introducing unacceptable side-effects. These standards have greatly encouraged to bridge the real-time physical world's applications/objects to cyber world for diverse range of time-critical applications. The communication and computing capabilities of cyber core are utilized to control/monitor real world's objects/applications. KeywordsThe performance of CPS depends upon QoS of the underlying network. In practice, applications' requirements vary in different environments. For example, in case of environmental surveillance, alarm packet should be prioritized as compared to normal data readings. In WBANs, life critical physiological readings should be delivered on time to the health services provider. However, IEEE 802.15.4 does not have such
