Analysis of embedded CORBA middleware performance on urban distributed transportation equipments

The increasing number of ITS (Intelligent Transportation Systems) equipment spread across cities offers tre- mendous possibilities in the development of distributed smart environments. A middleware layer located be- tween the operating system and the fi nal 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 quanti fi ed as it can affect the main application. This paper de fi nes a methodology for such quanti fi cation using as case example a modern ITS equipment related to vehicle tracking using arti fi cial vision. Experimental results illustrate the proposed methodology.Ministerio de Educación y Ciencia DPI2007-60128Consejería de Innovación, Ciencia y Empresa P07-TIC-0262
