Mercator: Self-organizing Geographic Connectivity Maps for Scalable Ad-Hoc Routing [chapter]

Luis A. Hernando, Unai Arronategui
Lecture Notes in Computer Science  
We propose a method based on the discovery of connectivity between geographic regions that are self-organized in a multilevel hierarchy.  ...  The Mercator protocol builds lightweight connectivity maps in a fully decentralized manner and shows a scalable and resilient behaviour.  ...  Introduction A fundamental problem of future ad-hoc networks is to get self-organized routing protocols with good scalability properties and good enough paths.  ...

3D maps distribution of self-driving vehicles using roadside edges

Masaya Mizutani, Manabu Tsukada, Yuki Iida, Hiroshi Esaki
2020 2020 Eighth International Symposium on Computing and Networking Workshops (CANDARW)  
Point Cloud Data (PCD) maps are used for scan matching to enable self-localization.  ...  Subsequently, we evaluate whether the autonomous vehicle can simultaneously download the PCD map from its edge and enable self-localization.  ...  Vehicles and infrastructure communicate on the vehicular ad hoc network (VANET), which is realized through P2P communication.  ...
