Experimental assessment of using network coding and cooperative diversity techniques in IEEE 802.15.4 wireless sensor networks

Abstract

The use of wireless sensor networks (WSN) to support critical monitoring applications is becoming a relevant topic of interest. These networks allow a highly flexible approach to data monitoring and, consequently, a major breakthrough for several application domains, from industrial control applications to large building domotics and health care applications. One of the major impairments of using wireless networks to support critical monitoring applications is the electromagnetic noise, which may increase the packet loss ratio to unacceptable values. In this paper, we assess different techniques of cooperative communication and network coding that can be useful to mitigate the aforementioned problem. These techniques may be implemented in WSN nodes in conformance with the IEEE 802.15.4 standard, to reduce the impact of electromagnetic interferences upon the packet loss ratio. In this paper, we report an experimental assessment of the network coding and cooperative diversity techniques, where the network is subjected to a controlled electromagnetic interference inside of an anechoic chamber. The experimental results show that, by using these techniques, it is possible to increase the success rate of communication in typical electromagnetic noisy environments.

First Stage Cooperative Network Coding for Wireless Sensor Network

“…In [13], [14], and [15], most recent work applied over WSN which has applied CoNC with different important techniques and we believe it gives good and important knowledge for the most updated CoNC WSN techniques which are unlike the proposed work in this paper mainly because our proposed CoNC starts in the first stage and being applied in each half stage rathe r than each full stage.…”

Bit and Packet Error Rate evaluations for Half-Cycle stage cooperation on 6G wireless networks

“…The most recent work for the application of CoNC on the physical layer has been presented in [22], where soft and hard decision encoder-decoder PUMTC was used to show the advantages of performance of the softdecision encoder-decoder over the hard-decision, on a cluster of Wireless Sensor Networks (WSNs). More related work on using CoNC on WSN application was introduced in [23][24][25], where in [23] the CoNC improved the diversity. In [24], a cooperative relay was proposed to enhance the mechanism of the retransmission, and in [25], CoNC was applied to improve the routing performance.…”

Experimental assessment of LNC‐based cooperative communication schemes using commercial off‐the‐shelf wireless sensor network nodes

“…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.…”

“…It can be argued that for networks with larger number of nodes, or with a significant packet error rate (PER), a more effective solution would be to use linear network coding (LNC) techniques, which are able to encode multiple messages into single messages . In the literature, there are some works dealing with the reduction of encoding/decoding complexity .…”
