“…Direct FEC coding of entire packets at source has an obvious drawback -in this case, every forwarding node must decode the whole packet to extract the forwarding information and encode the whole packet again if forwarding criteria are fulfilled, which results in higher workload for all sensor nodes and higher energy consumption. Therefore, we combine the IEEE 802.15.4-compliant FEC coding scheme from [14] with the previously defined lightweight routing approach.…”

“…In [13] a directed flooding scheme is proposed, but, despite significant energy savings, the transmission reliability remains equal to the one of the regular flooding scheme. Although there exist numerous works on Forward Error Correction (FEC) for WSNs, only [14] (and references therein) and [15] provide packet-level implementation details. Furthermore, to the best of our knowledge, no solution that blends lightweight routing with FEC coding for WSNs can be found in the literature.…”

Abstract-In this paper we address the issues of timeliness and transmission reliability of existing industrial communication standards. We combine a Forward Error Correction coding scheme on the Medium Access Control layer with a lightweight routing protocol to form an IEEE 802.15.4-conformable solution, which can be implemented into already existing hardware without violating the standard. After laying the theoretical foundations, we conduct a performance evaluation of the proposed solution. The results show a substantial gain in reliability and reduced latency, compared to the uncoded transmissions, as well as common Wireless Sensor Network routing protocols. I. INTRODUCTIONThe research efforts to introduce Wireless Sensor Networks (WSN) into Process Automation (PA) have produced three major industrial communication standards: WirelessHART [1], ISA100.11a [2] and WIA-PA [3]. The solutions based on these specifications shall satisfy the stringent performance requirements of PA applications and collect the sensor data in a reliable and timely manner. Nevertheless, a number of field tests, such as [4], reveal the fact that high communication reliability and real time performance can hardly be achieved. Some downsides of the existing solutions are worth mentioning. Routing protocols encountered in existing industrial communication standards are overcomplicated. Path failures in a dynamic environment (such as industrial) are frequent, triggering tedious path recalculation processes, during which transmission of data traffic is put on hold. Control message overhead is a natural side effect in such an environment, and exchange of routing tables, beacons and other control messages consumes bandwidth; Error Control and Correction: industrial communication standards do not approach the problem of error control in a preemptive manner. Instead, packet retransmissions are employed, which may boost the data latency in the network and deliver outdated data to the sink. Consequently, rethinking of current designs deserves consideration.Flooding is the most rudimentary routing technique and flooding-based algorithms are often seen as a way to simplify data dissemination in WSNs. Traditional flooding approaches suffer from broadcast storm and energy inefficiency problems, which were thoroughly studied in [5] and [6]. The floodingbased schemes presented in [7], [8], [9] and [10] are designed for broadcast traffic. However, the aim of this work is to simplify sensor data collection, rather than point-to-multipoint communication. Flooding-based routing schemes encountered

“…Considering IEEE802.15.4-based [5] IWSNs, the low-level reference standard used in WirelessHART and ISA100.11a systems [6], few FEC-based techniques have been proposed over the years. In [7], and in its enhanced version [8], a FECbased technique to be implemented at Media Access Control (MAC) layer is proposed by considering Reed Solomon (RS) and Bose and Ray-Chaudhuri (BCH) codes to protect both header fields and payload. In both works the backward compatibility with the IEEE802.15.4 standard is maintained, as well as an increased communication reliability is achieved at the cost of an additional overhead in terms of computational power for data decoding purposes.…”

Industrial Wireless Sensor Networks (IWSNs) are nowadays becoming more and more popular thanks to their flexibility and pervasive monitoring capabilities to support process automation and remote maintenance applications. In such a scenario, channel errors due to the wireless medium can result in data packet losses, and consequently in unreliable IWSN services. To mitigate the above reported problem, this paper presents a lightweight error correction scheme specially developed for IEEE802.15.4-based IWSNs. By adding error correction and detection information inside the IEEE802.15.4 MAC data frame, the proposed FEC scheme is able to guarantee a backward compatibility with the standard while providing advanced capabilities in recovering data packets affected by bit errors. In the paper the benefits of the proposed technique are first evaluated through simulated loss traces, then they are validated in a real environment by considering real loss traces collected in an electricity power plant. The proposed error correction scheme is able to recover around 50% of the data packets that would be lost in case of a standard communication without any error correction capability

“…Results of [15] which characterize channels based on Line of Sight (LOS) and link quality are taken as additional input to decide upon relay placements. An attempt to use FEC for reliable 802.15.4 based IWSNs was made in [16]. We use Link Quality Indicator (LQI) provided by the standard as a representative of RSSI and SNR to decide upon retransmission methodology.…”

Industrial Wireless Sensor Networks (IWSNs) adopted for wireless factory automation demand highly reliable, robust and delay sensitive communications over an interference prone and harsh channel conditions existing in factory environments. IEEE 802.15.4e Low Latency Deterministic Network (LLDN) mode is the latest in IWSN standards which attempt to satisfy these requirements assuming controlled RF environment with frequency planning. However, realistic indoor factory environments suffer from interference as well as multipath fading resulting in frequent packet losses, thereby affecting the communication reliability in terms of drop in overall Packet Delivery Ratio (PDR). To improve the reliability there are two important approaches, first cooperative diversity using relay nodes and second incorporation of Forward Error Correction (FEC) techniques, both of which are not available in the aforementioned standard. Hence, to enhance the reliability offered by 802.15.4e LLDN, we have proposed a two-fold solution in this paper. First an efficient and realistic relay node placement strategy based on Rainbow Product Ranking algorithm and second an Adaptive Retransmission scheme using selective cooperative diversity and Reed Solomon (RS) block codes.
