So far, only the addressing of larger two-dimensional areas was possible. For the use in an urban environment it is crucial that small and three-dimensional areas can be addressed. For example, GeoCast can then be used to send lecture notes to all in a classroom. In this paper we describe a fine-grained addressing concept for GeoCast that supports such areas. In addition we present an architecture that allows the use of that addressing concept together with the GeoRouting-approach developed by Navas and Imielinski. We also present some modifications necessary to enhance the scalability of GeoCast.eninfo:eu-repo/semantics/openAccessLokalisation , Datenfunknetz , Mobilfunk , Tragbarer Personalcomputer , Datenübertragung , Adressierung004GeoCast , Nexus , Mobile ComputingworkingPaper2013-07-04
