چکیده

This paper deals with the description in E-Lotos of the asynchronous Link layer protocol of the Ieee-1394 Standard and its veriication using model-checking. The E-Lotos descriptions are based on both the standard and the Crl description written by Luttik. The veriications are performed using the Cadp (CCsar/Ald ebaran) toolbox. We translate the E-Lotos descriptions in Lotos using the Traian tool, and then we generate the underlying Lts models corresponding to various scenarios using the CCsar compiler. We formally express in the Actl temporal logic the ve correctness properties of the Link layer protocol stated in natural language by Luttik and we verify them on the Lts models using the Xtl model-checker. We detect and correct a potential deadlock caused by the ambiguous semantics of the state machines given in the standard, which can be misleading for implementors of the Ieee-1394 protocol. Validation du protocole de la couche liaison du bus s erie IEEE-1394 (\FireWire") : une exp erience avec E-LOTOS R esum e : Ce rapport pr esente la description en E-Lotos de la partie asynchrone du protocole de la couche liaison du standard Ieee-1394 et sa v eriication en utilisant l'approche bas ee sur les mod eles (model-checking). La description E-Lotos est bas ee sur le standard et sur la description ecrite en Crl par Luttik. Les v eriications sont eeectu ees en utilisant la bo^ te a outils Cadp (CCsar/Ald ebaran). La description E-Lotos est traduite en Lotos a l'aide de l'outil Traian et les mod eles Ste sous-jacents sont g en er es a l'aide du compilateur CCsar. Nous avons exprim e en logique temporelle Actl les cinq propri et es de correction du protocole de la couche liaison formul ees en langage naturel par Luttik et nous les avons v erii ees sur les mod eles Ste a l'aide de l' evaluateur Xtl. Nous avons d etect e et corrig e un blocage potentiel d^ u a la s emantique ambigu e des machines d' etats donn ees dans le standard qui peut induire en erreur les impl ementeurs du protocole Ieee-1394.

Emulation and Validation of a 4g System Proposal

This paper presents a wireless link and network emulator, along with experiments and validation against the “Wireless IP” 4G system proposal from Uppsala University and partners. In wireless fading downlinks (base to terminals) link-level frames are scheduled and the transmission is adapted on a fast time scale. With fast link adaptation and fast link level retransmission, the fading properties...

A Flexible Link Radar Control Based on Type-2 Fuzzy Systems

An adaptive neuro fuzzy inference system based on interval Gaussian type-2 fuzzy sets in the antecedent part and Gaussian type-1 fuzzy sets as coefficients of linear combination of input variables in the consequent part is presented in this paper. The capability of the proposed method (we named ANFIS2) for function approximation and dynamical system identification is remarkable. The structure o...

Low-speed impact behavior of two-layer similar and dissimilar metal laminate structures

Mechanical behavior of two-layer metal laminate structures under low-speed impact loading was investigated experimentally and numerically. The experimental results were just used for validation of numerical results. Then numerical modeling was used to study the behavior of metal laminates in details. The mechanical behavior of the metal laminate structures under impact loading was found to be d...
