Abstract: Nowadays, Smartphones supports a vast range of applications but in return demands a very high computational power increasing with time. But as we know Smartphone’s computation power, memory, storage, and energy are limited solution to this problem can be Cloud Computing that offers a very wide computational power, memory, storage and energy. Hence, Researches are aiming to get Cloud Computing for smartphones to fulfil its requirements. But the traditional Smartphone application models not supporting the cloud computing features and requires specialized mobile cloud application models has became a challenge for the researchers. This article covers mobile cloud architecture, decision affecting entities on offloading, classification of application models, the latest mobile cloud application models and their critical analysis.

Keywords: Cloud, Mobile Cloud, Application Models, Survey of Mobile Cloud.
