“…If the source node cannot find the problem in time, the entire scheme will fail. Therefore, redundancy strategies have been adopted in several optimized schemes [3][4][5] by which in-network nodes generate and transmit additional coded packets. In this way, these schemes ensure that a destination node can supplement the width of the decoding coefficient matrix by substituting these linear dependent vectors.…”

“…Network coding provides an appropriate approach to solve these problems. [2][3][4][5] Since Ahlswede and Cai 6 first proposed the principle of network coding, many scientific researchers have shown strong interest in this area. 7,8 Because a network coding protocol can utilize network bandwidth more reasonably, it can significantly improve network performance in MWSNs that use multicast.…”

In mobile wireless sensor networks, linear network coding has been shown to improve the performance of network throughput and reduce delay. However, the linear dependence of coded packets caused by linear network coding will result in significant instability of the entire network during data transmission. Moreover, current linear network coding schemes do not distinguish between the real-time requirements of different packets. To solve the above problems, a weighted Vandermonde echelon fast coding scheme is proposed based on an analysis of various coding schemes such as random and linear network coding. Weighted Vandermonde echelon fast coding scheme can reduce the dependence problem of the network coding matrix and distinguish between different packet priorities. The accuracy of the proposed weighted Vandermonde echelon fast coding method is investigated through a theoretical analysis and then its outstanding delivery performance is verified through discrete event simulation experiments.

“…It is worth noting that none of these experimental assessments evaluated the packet decoding durations; instead, they only assess encoding and a linear combination of packets. The duration of decoding operations was not measured, presumably because for the case of star topologies, these operations can be performed by the network coordinator, which typically has larger processing capacity.…”

“…Typical drawbacks are the loss of connectivity or message corruption and, as a consequence, a loss of data packets, an increase of the delay jitter, an increased number of missed deadlines, and the loss of synchronization between network nodes . The use of network coding (NC) techniques to support cooperative communication has been proposed as a mean to increase the reliability of WSNs communication, for optimizing its bandwidth usage or for reducing its overall energy consumption . In essence, some cooperative relay nodes in the network combine multiple overheard messages into single messages using NC techniques, and at the destination arrival, the independent information will be reliably extracted.…”

Summary The use of wireless sensor network nodes to support reliable communication exposes some challenging issues. For instance, the reduced available bandwidth combined with an error‐prone communication medium impairs the provision of reliable communication services. Network coding techniques can be useful to mitigate some of these issues, where multiple message groups can be combined into single messages and retransmitted to their destinations, improving the network reliability and reducing the bandwidth consumption. However, an effective use of network coding requires the availability of wireless sensor network nodes able to encode/decode messages within the required timing constraints. This paper reports an experimental assessment of commercial off‐the‐shelf wireless sensor network nodes, running a set of network coding encoding/decoding tasks. The assessed nodes range from the high‐performance ARM Cortex‐M7 to the low capability Arduino Uno platforms, including some of the most popular ARM Cortex and ATMEL AVR processors. The performed experimental assessment demonstrates that highly complex network coding techniques (with fields as large as F28) can be efficiently implemented on a wide range of wireless sensor network nodes, including ARM Cortex, ATMEL AVR, and Arduino Uno platforms, smoothing some relevant reliable communication implementation issues.
