An embedded system for wireless data communications on trains

This paper presents a new wireless network sy.wm implemented on trains. This nehvork system provides communicatio~i sewices ,for data tran.sfir and system manugement roefiil Jbr infornrotion tran.~mi.ssion and train monitoring. It i . ~ hused on the Bliietrioth technolos. ~vhich i . ~ iised to inte~connecf the varions train cars to the locomotive. Every nehvork node is composed hy a powe~firl embedded sjsrem reqriired to control the Blnrtooth nehvork inrerfirce. We developed hoth hardware architecture and sojtx.are desigti of this emhedded sy.stem. which allows to 'achieve a,f& mid @cient implementation of'the protocols and a1gorith;is drsigned for the commiinication system management. Index terms Bluetooth technology, embedded system, logistics, wireless.
