“…All the nodes store all the received packets for possible packet-decoding purposes. Hence, a typical network-coding mechanism is composed of two main operations: (1) the coding of the outgoing packets on (intermediate) nodes and (2) the decoding of incoming packets upon their reception on nodes [19].…”

“…Network coding was originally proposed to increase the throughput of a single-source communication, for instance, a multicast stream [1], in order to achieve the maximum data-transfer rate in multicast networks [12]. In this paper, we are interested in opportunistic network coding, where the packets for transmission are selected in a classic manner and the coding opportunities are searched for only amongst the packets currently present in the output queue [10,13,19]. We further focus our interest in fixed, wireless mesh networks, such as metropolitan Wi-Fi networks [6] or Wireless Sensor Networks (WSNs) [22] with unicast traffic, where the nodes can be seen as fixed wireless access points for the end users.…”

“…The well-known and widely adopted COPE [10] has been under the spotlight, while so-called support mechanisms such as scheduling [21], queue management [7,16,17] and routing support [11,14,20] were used to bring about additional gains. Most of these support mechanisms can also be used with other opportunistic network-coding approaches, such as [3,8,19].…”

Practical experience of using opportunistic network coding has already been gained in several real network deployments, indicating the influence of some of the fundamental characteristics of the network and the traffic load. However, these aspects have not been systematically investigated in the scope of the construction of efficient and robust large-scale network-coding-enabled wireless mesh networks. In this paper we focus on these aspects using an example of two opportunistic networkcoding procedures: the well-known COPE and the Bearing Opportunistic Network coding (BON). In addition, the design aspects for network-coding-enabled wireless mesh networks and applications are discussed. We have shown that opportunistic network coding can improve the performance of different networks and supported applications in terms of throughput, delay and jitter, although the benefits are not significant in all the cases. Thus, the use of opportunistic network coding should be considered upfront during the wireless network design phase in order to obtain the greatest benefits.
