Communication link configuration method for wireless routing strategy in emergency communication

With the advancement of technology, China is developing rapidly in the construction of emergency communication systems. Currently, emergency communication networks have an urgent demand for multimedia services and higher requirements for network bandwidth. When there are multiple different services in the network, traditional universal routing protocols are no longer applicable and cannot simultaneously meet the transmission requirements of different business flows. There is a common problem with the existing encoding aware routing in the power emergency communication MESH network. In order to improve network performance, a large amount of data flow is concentrated on certain nodes to create more encoding opportunities. When the data flow increases to a certain extent, these nodes will cause local congestion or even paralysis due to heavy load. A new routing metric has been proposed, and based on this metric, a coding aware load balancing routing strategy has been proposed. This routing strategy not only utilizes network coding to save network resources and improve network throughput, but also considers the load situation of nodes. It selects nodes with relatively light load as the next hop node to forward, achieving a balance between network coding and node load balancing. The simulation results show that in scenarios with different data transmission rates, this routing strategy can effectively alleviate network congestion, with higher network throughput and lower end-to-end latency.
