A resources allocation algorithm based on media task QoS in cloud computing

Consider service satisfaction of multitask in cloud media, a resources allocation algorithm based on Media Task QoS (RAMTQ) is put forward. Firstly, according to media task features, QoS weight vector and expected resources vector are obtained; then we work out resources similarity vector between alternative resources and expected resources by linear normalization, further to obtain the service satisfaction by Euclidean distance; finally, the resources corresponding to the maximum service satisfaction are allocated. The simulation illustrates the effectiveness of the algorithm.
