Availability and Energy Consumption Analysis of Mobile Cloud Environments

Mobile cloud computing refers to abstraction of computational power to outside of the mobile device, processed in the "clouds". This paper provides an availability and energy consumption study using hierarchical heterogeneous modeling. Different scenarios were analyzed considering wireless communication technologies, such as 3G and WiFi. The results shows that the 3G protocol causes a lower availability and is the greater responsible for the discharge of battery, but when is combined with WiFi protocol providing communication redundancy, we have the best results of availability and better results of uninterrupted operation time of battery.
