lightweight virtualized evolved packet core Architecture for future mobile communication
Wireless Communications and Networking Conference, 2015Co-Authors: Hiroki Baba, Minoru Matsumoto, Katsunori NoritakeAbstract:The accommodation of machine-to-machine (M2M) terminals in mobile networks is important; therefore, future network Architecture supporting M2M services is of intense interest to mobile network operators. We propose an implemental Architecture of a virtualized evolved packet core (vEPC) to accommodate M2M services. The Proposed Architecture deploys dedicated vEPCs based on the functional requirements of services. Every vEPC is optimized by eliminating EPC components or replacing standardized interface protocols with internal application interworking. We confirm the validity of the Proposed Architecture by experimentally evaluating CPU resource consumption. We also confirm that the Proposed Architecture reduces CPU time consumption by up to 27% by reducing signaling message volume, and improved performance is observed independently with M2M terminal mobility or communication characteristics.

Performance Analysis of a Proposed Architecture for Remote Construction Machines Diagnostics
Proceedings of the Third International Afro-European Conference for Industrial Advancement — AECIA 2016, 2018Co-Authors: Ousmane Sadio, Ibrahima Ngom, Claude LishouAbstract:The vehicle industry manufacturer is showing an increased interest in remote diagnostics by improving customer relationship management and commercial interest. The special nature of construction machines fact that Architectures and applications Proposed for vehicular communication are not optimized for these types of vehicles. This paper proposes a new remote diagnostic Architecture based on IEEE 802.11n for construction machines communication to the infrastructure on site. The mobile Internet is used to transmit collected data to the central monitoring application. We discuss the possible network selection algorithms, mobility and security protocols that can be implemented on the On Board Units (OBU). The Proposed Architecture is based on Host Identity Protocol (HIP). This protocol introduces a Host Identifier (HI) for naming the endpoints and use intensive cryptographic operation for security and mobility management. Due to their minimal computing capabilities, many single board computers used as OBU themselves suffer from applications which need intensive CPU usage. Thus, a performance analysis of HIP, implemented on single board computers, is Proposed by the end of this paper.

PaCT - Further Pipelining and Multithreading to Improve RISC Processor Speed. A Proposed Architecture and Simulation Results
Lecture Notes in Computer Science, 1995Co-Authors: Bernard GoossensAbstract:This paper presents a new pipeline Architecture which should improve both the number of Cycles Per Instruction (CPI) and the cycle width. The pipe stage critical path, imposed by the 64 bits integer unit, has been cut in half by data slicing and pipelining the Arithmetic and Logic Unit (ALU). Moreover, because this Proposed pipeline stages division should impose a very long latency for CPU external accesses, a multithreading structure has been included. Up to four threads may be simultaneously run with a no delay context switch. Thus, multithreading is mainly used as a latency hiding technique for external accesses and internal dependencies. In order to estimate the real benefit of the construct, a simulator has been built. Simulation results show the impact of pipeline improvements without multithreading (between 24% and 32% according to cache size) and with it (from 56% to 65% with four threads and same caches).

a comprehensive review and Proposed Architecture for offshore power system
International Journal of Electrical Power & Energy Systems, 2019Co-Authors: Rodney Itiki, Silvio Giuseppe Di Santo, Cinthia Itiki, Madhav Manjrekar, Badrul H ChowdhuryAbstract:Abstract This review describes the offshore power system (OffPS), a research area of electricity that—despite being deeply investigated in scattered fragments—has not been comprehensively conceptualized as an integral system of interrelated components, equipment, functions and subsystems. Part of this lack of systemic approach is due to the fact that this system normally does not subsist by itself. It depends on structural elements for protection and support. OffPS gathers all the characteristics of a system and has several configurations, subsystems, and functions. In many cases, OffPS is subjected to extreme forces imposed by offshore weather conditions. For this reason, it is duly enclosed, protected and supported by several offshore-resistant mechanical machines such as ships, submarines, offshore platforms, floating ports and power plants. The prevalence of OffPS has been geographically expanding in recent years and it is spreading over vast portions of the oceans. On a larger extent, it is evolving towards an offshore power grid, a network that connects countries and even entire continents. It is also adjusting to multi-agent power access, in what is called multi-terminal OffPS. In order to encompass such a variety of topologies and applications, a generalized Architecture of OffPS is Proposed. It establishes a basic framework for this review on the latest research advances in offshore power generation, transmission, distribution, consumption, energy storage, offshore intelligence and environment. Nuances between specific offshore power systems, influences of the surrounding environment, interactions between OffPS subsystems and other research areas are then described within this framework. The aim of this review is to facilitate a better systemic understanding of the major challenges and importance of offshore power system research in contemporary society.
