Energy consumption in data center has already become a widely concerned issue in cloud computing research. There are many studies on data center energy efficiency optimization. But most of them focus on the energy consumption of the servers and cooling equipment. Few of them considered data center network (DCN), which is also a significant energy consuming component. By applying newly emerged Software...
With the rapid development of the cloud computing, personal health record (PHR) has attracted great attention of many researchers all over the world recently. However, PHR, which is often outsourced to be stored at a third party, has many security and efficiency issues. Therefore, the study of secure and efficient Personal Health Record Scheme to protect users' privacy in PHR files is of great significance...
Based on the existing load balancing algorithm, aiming at the “hotspot” data accessed in P2P systems, a load balancing algorithm for heterogeneous P2P systems using mobile agent is proposed, which effectively balances loads of peers distributed among P2P systems with the help of autonomous agent called Mobile Agent. Experimental data shows that the algorithm greatly reduces the communication costs,...
