Dependability analysis of WRT54GL router

The paper presents the methodology, techniques and achieved results of dependability analysis of popular WRT54GL routers using complex Software Implemented Fault Injection (SWIFI) system. Several problems and their solutions are discussed and presented, for instance, the SWIFI in embedded system, high controllability over the injected faults and observability of their effects, and the automation of the experiments. They are presented on the background of the achieved dependability results.
