Abstract

Intelligent freight objects can simplify the solution of complex logistical planning tasks by splitting the problems to locally executable subtasks. The concept of Ubiquitous Computing (UbiComp) presents a model to realize such intelligent objects. A local task can be handled autonomously by a group of objects. The realization of UbiComp needs a platform that a) provides computation resources for implementation of decision algorithms and b) position information in order to enable context-aware features. This article presents a concept for the autonomous supervision of perishable goods and introduces the required soft- and hardware. Freight objects are represented by individual software bundles. The signal strength of an RFID reader is used to provide position information by a cell based localization. A new approach is presented, where four RFID antennas are used to locate goods in inside a container.
