Design and simulation of EB-RPL protocol in 5G intelligent power plant application scenario

5G can better meet the security, reliability and flexibility requirements of power grid business, and realize differentiated service guarantee. This paper focuses on the application scenarios of 5g smart power plant, and studies the applicable routing protocol and optimization scheme. The existing RPL uses a single link quality expected transmission times as the routing metric to calculate and compare the optimal paths. However, when some nodes in the network consume too much energy due to uneven load, the topology cannot be dynamically adjusted according to the routing metrics. In this paper, energy consumption is introduced to calculate the energy consumption of nodes. Combined with the expected number of transmissions, an improved RPL routing algorithm nb-npl based on energy balance is proposed. The algorithm not only takes into account the reliability of the link, but also considers the energy consumption information of the node, so that the node can avoid selecting those nodes with more energy consumption in the default routing selection process, which solves the problem that individual nodes are always in heavy use, and effectively performs the network life.
