Analysis of embedded CORBA middleware performance on urban distributed transportation equipments

The increasing number of ITS (Intelligent Transportation Systems) equipment spread across cities offers tremendous possibilities in the development of distributed smart environments. A middleware layer located between the operating system and the final application can be used for the communication among the equipment to spontaneously act and cooperate among themselves. However, this middleware layer has also a computational cost that should be quantified as it can affect the main application. This paper defines a methodology for such quantification using as case example a modern ITS equipment related to vehicle tracking using artificial vision. Experimental results illustrate the proposed methodology.

► Methodology for and quantifying embedded middleware performance.
► It uses shell utilities and system calls defined in the POSIX family of standards.
► Comparative analysis of MICO and TAO implementations of CORBA.
► Evaluation of load-balancing mechanism for client requests..
