According to the important methodology of convex optimization theory, the energy-efficient and scalability problems of modern data centers are studied. Then a novel virtual machine (VM) placement scheme is proposed for solving these problems in large scale. Firstly, by referring the definition of VM placement fairness and utility function, the basic(More)
Based on the convex optimization theory, the energy-efficient and scalability problems of modern data centers are studied. Then a novel application-aware virtual machine (VM) placement algorithm is proposed to cope with these problems. Firstly, the definition of VM placement fairness and utility function are given, and the basic algorithm of VM placement(More)
Over the past few years, modern mobile subscriber devices such as Smartphones, tablets and PDAs have become more and more popular which use network resources in a more aggressive way and last for longer durations involving dramatically increasing traffic volumes. But traditional mobility management schemes have hardly taken this issue into account.(More)
It is believed that traditional centralized mobility management cannot satisfy the demands of mobile data traffic which has dramatically expanded for years and will remain at a high growth rate in the long term. And now many efforts are putting emphasis on developing distributed mobility management schemes. This paper discusses the advantages of multiple(More)
