Improved AOMDV Routing Protocol in Manet UAV Based on Virtual Hop

摘要

In order to improve the load balancing capability of the AOMDV routing protocol of the ad hoc network, the network nodes are divided into two levels, Risk and No risk, based on the queue buffer ratio, and a different processing is done for different levels. Directly remove the risk level nodes and assign the corresponding virtual hops to the No Risk level nodes via the threshold comparison. The higher the queue cache rate, the higher the corresponding virtual hops. The RREP and Hello messages are expanded, and the node queue cache ratio is added to update and collect the latest path node status information. The improved protocol uses the minimum virtual hops containing node load information as the basis for optimal path selection, and uses OPNET to simulate at a fixed node rate under different network loads. The results show that the improved routing protocol plays a role in load balancing for nodes at the expense of limited routing overhead, relieves network congestion, increases the packet delivery rate, effectively reduces the end-to-end transmission delay, and improves self-organization. Network performance provides a relatively simple method.
