Abstract:

With regard to the issue of energy consumption while reallocating resources for service image placement system in MCC (Mobile Cloud Computing), it adds a wireless channel condition Monitoring module on the basis of the existing service image placement system, then proposes an improved scheme for reallocating resources. According to the users moving situation, the system doesn't reallocate resources when users quality of service is in the accepted scope, thus saving energy for system. It determines the accepted scope according to the simulation result. Compared with the newest simulation result, the improved algorithm can save energy consumption of system by 30%.

Key words: mobile cloud computing (MCC), service image placement system, reallocate resources, quality of service, energy-saving
