For providing an efficient discovery with a best possible reduction of network usage and/or computation time a method for discovering a set of objects within a defined geographical space is claimed, wherein the objects match at least one predefined characteristic and wherein object information regarding the at least one predefined characteristic is provided by different servers, comprising the following steps: discovering objects within the defined geographical space by a geo discovery request based on geographical coordinates; finding − from the discovered objects − a starting object matching the at least one predefined characteristic within a definable sub-space of the defined geographical space; ranking the objects within the definable sub-space by increasing distance to the starting object within a rank; sending a query to the servers for gathering object information regarding the first object in the rank which is located nearest to the starting object; checking whether the first object matches the at least one predefined characteristic; repeating the sending and checking steps regarding the further objects in the rank and according to the ranking of increasing distance, until a minimum set of objects matching the at least one predefined characteristic is discovered. Further, an according network for carrying out the method is claimed. |
