“…Broadcasting is the term used to describe communication where the data packets are sent from one node to all other connected nodes; a single sender transmits data, and the data is sent to all connected receivers. Network coding reduces energy consumption in WSNs by reducing the number of transmissions required in a network to carry traffic between the set of sources and the set of destinations [1,16,19,35,40]. The deployment of network coding and broadcasting realizes significant benefits in terms of resource and energy management and improves a network's throughput, efficiency and scalability, as well as resilience to attacks and eavesdropping [24].…”

Wireless sensor networks (WSNs) are widely deployed to support transmissions of the huge data emitted by heterogeneous connected devices. The quality of service (QoS) and energy requirements in WSNs are dramatically increasing and becoming challenging issues. Integrating network coding, in the data transmission process, leads to reduced energy consumption and improved QoS. In this work, we study the problem of energy efficiency in multi-hop WSNs, namely wireless unsplittable multi-commodity flow with network coding (wUMCFC). We propose mixed-integer programming formulations of the wUMCFC problem, and we implement an open source solver wUMCFC based on the branch-and-price algorithm. To the best of our knowledge, this work is the first study of the wUMCFC problem by mathematical programming tools. We perform a computational study on realistic instances with an analysis of the performance of the proposed algorithm. The computational results show the efficiency of the network coding and provide important information for strategic decisions on routing policies and network management https://github.com/ lidingxu/wUMCFC.

“…Such protocols include HARQ-chase combining (HARQ-CC) [235], NOMA-HARQ [236], and HARQ-incremental redundancy (HARQ-IR) [237]. Other techniques such as network slicing [238], [239], network coding [240], [241], and control channel design [242], [243], can be beneficial to ensuring efficient retransmission and increasing the reliability of the network for PM applications.…”

Enabling Precision Medicine via Contemporary and Future Communication Technologies: A Survey

2023

Precision medicine (PM) is an innovative medical approach that considers differences in the individuals' omics, medical histories, lifestyles, and environmental information in treating diseases. To fully achieve the envisaged gains of PM, various contemporary and future technologies have to be employed, among which are nanotechnology, sensor network, big data, and artificial intelligence. These technologies and other applications require a communication network that will enable them to work in tandem for the benefit of PM. Hence, communication technology serves as the nervous system of PM, without which the entire system collapses. Therefore, it is essential to explore and determine the candidate communication technology requirements that can guarantee the envisioned gains of PM. To the best of our knowledge, no work exploring how communication technology directly impacts the development and deployment of PM solutions exists. This survey paper is designed to stimulate discussions on PM from the communication engineering perspective. We introduce the fundamentals of PM and the demands in terms of quality of service that each of the enabling technologies of PM places on the communication network. We explore the information in the literature to suggest the ideal metric values of the key performance indicators for the implementation of the different components of PM. The comparative analysis of the suitability of the contemporary and future communication technologies for PM implementation is discussed. Finally, some open research challenges for the candidate communication technologies that will enable the full implementation of PM solutions are highlighted.INDEX TERMS Precision medicine, fourth industrial revolution (4IR) technologies, communication technologies, 5G, 6G.
