Flow control of ship wireless network nodes considering load and delay
In response to the problem of poor stability,load imbalance,and high information transmission delay in ship wireless networks,a flow control method for ship wireless network nodes considering load and delay is studied.This meth-od utilizes directed graphs to optimize the wireless network structure and node hierarchy of ships;Calculate the load occu-pancy rate and availability rate of ship wireless network nodes,and extract the load balanced node communication path;Us-ing RTT based congestion flow allocation algorithm with the goal of reducing latency,to achieve traffic control for ship wireless network nodes considering load and latency.The experimental results show that after using this method,the group delivery rate of ship emergency services,critical services,and ordinary services in the wireless network is improved,solving the problem of load imbalance;The end-to-end latency for emergency services is less than 100 ms,while the end-to-end latency for critical and regular services is less than 1 000 ms,resulting in better traffic control effects.
