Article: Heterogeneous communication architecture for the smart grid
[show abstract] [hide abstract]
ABSTRACT: The smart grid concept provides a solution to the growing recognition that current utility grids need an ICT deployment infrastructure based upgrade to allow millions of potential market players to operate and to cope with distributed generation, wide-area situational awareness, demand response, electric storage, and efficient electric transportation. Smart grid deployment is mainly about defining the necessary standards for ICT solutions. The design of the communication network associated with the smart grid involves detailed analysis of its communication requirements, a proposal of the appropriate protocol architecture, the choice of the most suitable technologies for each case study, and a scheme for the resultant heterogeneous network management system. Given the smart grid use cases, this article is focused on proposing a heterogeneous communication paradigm for smart grids based on power line communications and wireless networks. The proposal is related to the framework of the ITU ubiquitous sensor network architecture using the ITU next-generation network model. This architecture allows for better management of the QoS in the smart grid and should facilitate interoperability with other technologies.IEEE Network 11/2011; · 2.24 Impact Factor -
Conference Proceeding: Issues of QoS Multipath Routing Protocol for SEN's Data Networks
[show abstract] [hide abstract]
ABSTRACT: This paper presents several considerations that must be taken into account in the design of a QoS multipath routing protocol suitable for Smart Electricity Networks (SENs). The main goal is the analysis of routing requirements that will make possible a future formal specification of a QoS aware multipath routing algorithm for the coming SENs' data networks in high voltage segment, whose long-distance mesh data networks will be a future challenge for engineering and research. In this paper, the study is focused on requirements specification regarding to distance-vector routing algorithms that reduce the overall overhead of routing information needed in the network, preserving the scalability feature.Telecommunications (AICT), 2010 Sixth Advanced International Conference on; 06/2010 -
Article: Survey and Performance Comparison of AMR Over PLC Standards
[show abstract] [hide abstract]
ABSTRACT: Automatic meter reading (AMR) is an application implemented by power utilities which is becoming increasingly important in the utilities sector. It could be included in the more general environment of demand side management, which satisfies the need for more improved communications. AMR offers a better financial return due to the inclusion of other applications. Although there are several international standards which address AMR, most deployments are currently using proprietary systems. This fact may reflect that current standards do not fully cover this area. Since the power network reaches all energy meters, a convenient way to deploy AMR is to use the power lines as a transmission medium. The present-day situation is that there is mounting pressure to deploy AMR systems in a bid to provide better management of the energy demand in a bid to reduce global warming and create a more sustainable electrical system in our environmentally conscious society. This paper is focused on analyzing different standards and specifications related to AMR over powerline communications (PLC). Furthermore, two of them are chosen, implemented, and simulated using the OPNET modeler. The main goal of the implemented applications is to obtain comparative results of the two most known standard applications in AMR over PLC.IEEE Transactions on Power Delivery 05/2009; · 1.35 Impact Factor -
Conference Proceeding: QoS Broker based architecture design for the PLC access network
[show abstract] [hide abstract]
ABSTRACT: Broadband PLC seems to be gaining popularity as an access network technology so that the standardization efforts are rising notably. Broadband PLC gives the opportunity of delivering services such as telephony, TV and Internet through the power line, but also entails managing the quality of service that these applications need. In this paper, a centralized quality of service architecture for PLC access networks based on a QoS Broker is proposed. This architecture will allow for better managing of the QoS in the PLC domain and it should facilitate the interoperability with other technology domains. PLC Qos Broker architecture must be integrated with the core network in order to attain end-to-end QoS.Power Line Communications and Its Applications, 2009. ISPLC 2009.

Conference Proceeding: Implementation of Traffic Engineering in NGNs Using Hybrid Genetic Algorithms
[show abstract] [hide abstract]
ABSTRACT: Traffic engineering, particularly routing optimization, is one of the most important aspects to take into account when providing QoS in next generation networks (NGN). The problem of weight setting with conventional link state routing protocols for routing optimization has been object of study by a few authors. To solve this problem for big networks artificial intelligence heuristics have been used, in concrete genetic algorithms (GA). Some of the proposals incorporate local search procedures in order to optimize the GA results, in the so-called hybrid genetic algorithm (HGA) or memetic algorithm. This paper presents an inedited comparative analysis of the main hybrid genetic algorithms (HGA) proposals, as well as comparing them with other algorithms for the same problem by means of simulations. One of the HGA algorithms was chosen from the results analysis and was implemented over a real testbed with commercial routers with successful OSPFv3 routing optimization.Systems and Networks Communications, 2008.
