Therefore, our work focuses on improving geographic routing. We aim to solve two core problems. First, how can we efficiently diffuse the location updates of a moving destination node across multiple hops with minimal overhead, without flooding the entire network? Second, in a dynamic neighborhood with potentially imperfect location information, how can we select a next-hop forwarder that offers the best balance between geographic progress and link stability? Solving these problems is key to improving packet delivery rate and saving energy. |
