The standardisation of the 10 GB-capable passive optical network (XG-PON) system is accompanied by a rigorous set of recommendations. Power reduction in XG-PONs is considered a quite important topic by the telecommunication standardisation sector (ITU-T), thus, with importance of energy saving, XG-PON recommendation describes power management processes in detail. The core power management process comprises distinct states representing the desired power management transitions, while two modes: namely, the doze and the cyclic sleep mode, are defined. This study provides an analytical model for power consumption computation of an optical network unit (ONU), assuming that the two modes are enabled in the ONU operation. The presented analytical findings are verified by conducting extensive simulation experiments. Concurrently, the average time spent on doze and cyclic sleep states is provided.
Part 5: Agents (AGE)International audienceThe development of high-level behavior for autonomous robots is a time-consuming task even for experts. The Kouretes Statechart Editor (KSE) is a Computer-Aided Software Engineering (CASE) tool, which allows to easily specify a desired robot behavior as a statechart model utilizing a variety of base robot functionalities (vision, localization, locomotion, motion skills, communication) for the Monas robotic software architecture framework. This paper presents an extension to KSE, which allows defining generic agent behaviors using automatic framework-independent code generation, as long as the underlying framework is written in C++. This way a user can program physical (robots) or software agents that can be executed on any platform using any compatible software framework. This paper demonstrates the transparent use of the extended KSE in the SimSpark 3D soccer simulation and the Wumpus world
