“…In this way, the objective of this section is to describe state-of-the-art approaches that mainly deal with the relay selection procedures. Then, state-of-the-art selection schemes were classified into five categories, according to the criteria used for the relay selection: Link Quality Based [ 7 , 13 , 14 , 16 , 26 , 27 ], Link Quality and Energy Based [ 17 , 28 , 29 , 30 ], Link Quality and Neighborhood Based [ 15 , 21 ], Link Quality and Data Rate Based [ 31 , 32 ] and Random Relay Selection [ 22 ] ( Figure 2 ).…”

“…Finally, in this category, the relay selection is performed without considering any criteria; therefore, any node in the network can be selected as relay. Willig and Uhlemann [ 22 ] conducted a study about this topic and concluded that relay nodes do not need to be in specific positions, which often requires specific channel quality measurements. According to the authors, randomly selected relay nodes can also provide benefits to a WSN, improving its success rate.…”

“…To validate the relevance/pertinence of the proposed PRS and ARS relay updating schemes, in addition to comparing the two techniques among themselves, their performance was also compared to three state-of-the-art techniques: Completely Random selection [ 22 ], Random selection Around the Coordinator [ 21 ] and Opportunistic selection [ 7 ]. This subsection briefly describes these three state-of-the-art relay selection techniques.…”

“…Completely Random (CR) — A totally random technique [ 22 ] was considered for the selection of the relay nodes, without considering the quality of the communication link with the coordinator. To determine the number of relay nodes, it must be verified how many nodes are associated with the network.…”

“…A simulation assessment of both schemes was performed using the OMNeT++ tool [ 20 ]. The proposed approaches were compared with three state-of-the-art techniques: Opportunistic [ 7 ], which selects the cooperating nodes according to the network packet error rate, Random Around the Coordinator [ 21 ], which performs a random selection of the nodes that have an adequate communication link with the destination node and Completely Random relay selection [ 22 ], which performs a random selection from all the nodes of the network.…”

Wireless Sensor Networks (WSN) are enabler technologies for the implementation of the Internet of Things (IoT) concept. WSNs provide an adequate infrastructure for the last-link communication with smart objects. Nevertheless, the wireless communication medium being inherently unreliable, there is the need to increase its communication reliability. Techniques based on the use of cooperative communication concepts are one of the ways to achieve this target. Within cooperative communication techniques, nodes selected as relays transmit not only their own data, but also cooperate by retransmitting data from other nodes. A fundamental step to improve the communication reliability of WSNs is related to the use of efficient relay selection techniques. This paper proposes a relay selection technique based on multiple criteria to select the smallest number of relay nodes and, at the same time, to ensure an adequate operation of the network. Additionally, two relay updating schemes are also investigated, defining periodic and adaptive updating policies. The simulation results show that both proposed schemes, named Periodic Relay Selection and Adaptive Relay Selection, significantly improve the communication reliability of the network, when compared to other state-of-the-art relay selection schemes.

The purpose of this paper is to present ongoing PhD work that investigates both the cooperative diversity and techniques of network coding needed to improve communication reliability in wireless sensor networks. In this context, we propose a relay selection technique. It aims to select the smallest number of relay nodes under certain constraints. One of the main innovations is that this approach is formulated as an optimisation problem. In addition, we analyse the best approach for solving the proposed optimisation problem. The assessment results highlight that the proposed technique significantly improves the communication reliability of the network in comparison with the state-of-the-art techniques for selection of relay nodes. Network coding techniques will be tackled in the second stage of development of this research.
