Survey on Reducing Power Consumption in Peer to Peer System

Today, it is very crucial to reduce the consumption of natural resources, such as petroleum. In information system need of reducing electrical power consumption have been raised. There is large scope for reducing power consumption in network based applications. There are many solutions how to reduce the power consumption by servers e.g. by turning off servers which are not required to execute the requests. In this paper, we surveyed how the Round Robin Algorithm and Consumption Laxity Based Algorithm are used to reduce the power consumption of server in peer to peer system and their demerits also

A Process Migration Approach to Energy-efficient Computation in a cluster of Servers

Application processes have to be efficiently performed on servers in a cluster with respect to not only performance but also energy consumption. In this paper, we newly propose a process migration (MG) approach to energy-efficiently performing application processes on servers in a cluster. First, a client issues an application process to a server in a cluster. A process performed on a current server migrates to another server if the server is expected to consume smaller electric energy to perform the process than the current server and the deadline constraint on the process is satisfied on the server. In the evaluation, the total energy consumption of servers is shown to be smaller and the average execution time of each process to be shorter in the MG algorithm than the round robin and random algorithms

Análise de cocitações em múltiplas perspectivas sobre o tema green it / Multiple-perspective co-citation analysis on the green it theme

O desenvolvimento de atividades de Green IT (tecnologia da informação verde) ainda está em evolução, sendo que o estudo acerca do tema tem se intensificado conforme os anos. Sua aplicação teve origem com a preocupação sobre os impactos ambientais causados pela tecnologia da informação, abordando práticas e estudos que podem contribuir com a redução destes. O presente trabalho tem o objetivo de realizar a análise de cocitações em múltiplas perspectivas sobre o tema Green IT, por meio do uso do software CiteSpace®. Para tanto, empregou-se a explicação científica hipotético-dedutiva, as abordagens qualitativa e quantitativa e o referido procedimento de verificação da literatura. Por meio da pesquisa realizada, foi possível identificar os principais autores no tema pesquisado e os trabalhos mais relevantes. Este trabalho contribui para a área acadêmica, pois fundamenta as primeiras etapas de estudos de escopo e de revisões sistemáticas da literatura para demais pesquisadores da área de tecnologia da informação verde/computação verde

Green IT Model for Gulf Cooperation Council Organisations

This research aims to develop a Green IT model that suits the needs of the Gulf Cooperation Council (GCC) countries. A mix-methods approach that combines interviews with a survey was implemented to assess the model critically. The initial model developed for evaluating various Green models to assess the Governance, Social and Cultural, Information Technology and Green Management in GCC. The Green IT model aims to raise sustainability awareness in GCC countries based on their visions
