“…Simulation results show that both the proposed frameworks are energy efficient compared to ARQ schemes and FEC schemes, and suitable to prolong the clustered network lifespan as well as improve the reliability. (6) In the article of "Design of network coding based reliable sensor networks" in 2019 [7] , a mathematical model and a heuristic algorithm are proposed to plan for the best placement of encoding nodes while ensuring reliability. The experimental results show that the adequate number and placement of encoding nodes can be effectively determined, significantly enhancing the performance of constrained sensor networks using network coding.…”

“…In [6], the transmission of too many packets is avoided through the use of multiple gateways and failure scenarios. Sets of critical links, with very high packet-erasure probability, are seen as failure scenarios and encoding nodes are placed so that a hearing path is ensured for linear combinations to reach one of the gateways.…”

“…A P2P overlay network (distributed storage/retrieval system) is necessary to federate all gateways, ensuring the recovery of lost packets when non-lost related packets are forwarded towards different gateways. When comparing the approaches in [3] and [12] with the one in [6], the latter is suitable for network environments having predictable critical links (failure scenarios), while the approaches in [3] and [12] are suitable for network environments where packet loss location is not predictable. That is, as long as critical/failing links are clearly identified, the approach in [6] presents significant advantages because fewer coded packets are generated, allowing for longer network lifetimes and higher goodputs.…”

Wireless sensor devices are usually powered with limited non-rechargeable batteries. This energy can easily be depleted when no wise consumption procedures are used, leaving the sensor nonfunctional. As most of the energy is consumed during the transmission of data, developing efficient data manipulation and transmission approaches is crucial and still an open problem that attracts the attention of many research groups. In this article a directed acyclic graph (DAG) based dissemination approach, where clustering and network coding techniques are applied, is proposed. As a main goal, this work aims at improving the network reliability (ensure recovery of lost packets), while minimizing energy consumption and balancing load at gateways. The proposed approach is compared to state-of-art approaches in terms of network reliability and energy saving trade-off. Experimental results demonstrate the strong performance of the proposed work.

Energy consumption and packet loss are common concerns in wireless sensor networks. However, designing protocols to minimize both metrics becomes very challenging because these are competing goals. In this paper, a data dissemination approach is proposed that uses probabilistic network coding to achieve a balance between energy consumption and packet loss. A subset of the network nodes, forming a directed acyclic graph, is selected to perform the encoding process under a certain probability. These nodes are the ones responsible for data delivery towards the gateways. The encoding probability is based on the kind of packet received: the more innovative the packet is, the higher the probability of going through the encoding process. The results show that random linear network coding, under such conditions, is able to adequately minimize energy consumption and packet drops, while being a very practical solution.
