WebSep 24, 2024 · The neighbor node receiving the data packet is geographically closest to the position of the destination node. This process is called greedy forwarding in geographic routing. Early position-based routing protocols only used greedy forwarding, which cannot prevent frequent occurrence of local maximum traps. WebGreedy nearest neighbor is a version of the algorithm that works by choosing a treatment group member and then choosing a control group member that is the closest match. For example: For example: Choose …
