چکیده
The energy problem is one of the serious problems in the current large-scale storage systems need to be addressed urgently. In order to reduce the energy consumption of cloud storage system, and to meet the performance needs of users, this paper purposed a cloud storage system integrated green gear-shifting mechanism (GGSC): The frame designed a new data partitioning strategy, data replication management strategy and proposed energy gear-shifting mechanism based on the data partition and data replication management. Experiments based on Gridsim showthat: the energy consumption of gear-shifting mechanism is cost effective, which saved about 59% average energy at the expense of about 2ms average response time and the maximum energy savings is about 66%. Keywords-data partitioning; data replication management; gear-shifting mechanism

E2ARS : An Energy-Effective Adaptive Replication Strategy in Cloud Storage System
In order to solve the urgent issue of the energy consumption in the cloud storage system. An Energy-effective adaptive replication strategy (E2ARS) is proposed in this paper, in which data partition mechanism, minimal replicas determining model, replicas placement strategies and the adaptive gear-shifting mechanism are elaborately designed. We try to conserve the energy consumption while satisf...
متن کاملEvaluation of Peak Shifting and Energy Saving Potential of Ice Storage Based Air Conditioning Systems in Iran
Thermal energy storage (TES) system has been introduced as a practical facility for shifting load from peak hours to off-peak hours. Because of different energy consumption during day and night, peak and off peak period is created on load curve. Ice storage technology which is a kind of TES system, is implemented in different points of the world with the purpose of solving load shifting problem...
متن کاملDoS-Resistant Attribute-Based Encryption in Mobile Cloud Computing with Revocation
Security and privacy are very important challenges for outsourced private data over cloud storages. By taking Attribute-Based Encryption (ABE) for Access Control (AC) purpose we use fine-grained AC over cloud storage. In this paper, we extend previous Ciphertext Policy ABE (CP-ABE) schemes especially for mobile and resource-constrained devices in a cloud computing environment in two aspects, a ...

Internet of things (IoTs) is the newfound information architecture based on the internet that develops interactions between objects and services in a secure and reliable environment. As the availability of many smart devices rises, secure and scalable mass storage systems for aggregate data is required in IoTs applications. In this paper, we propose a new method for storing aggregate data in Io...
متن کاملDesign of an 8-speed Internal Gear Hub with a Rotary Control Mechanism for Bicycles
Original scientific paper This paper proposes a novel design of an 8-speed internal gear hub which consists of a distributed-flow-type planetary gear mechanism and a rotary gearshifting control mechanism. The distributed-flow-type planetary gear mechanism comprises two transmission units and one differential unit to provide eight forward gears. A clutching sequence table and a set of feasible s...
