Nowadays, smart phones are considered as an essential component of our daily life. These devices can be used in social communication, mobile commerce, as a mobile office, and in many other useful applications. But these devices have serious challenges such as a short battery lifetime and a limited storage and limited processing capacities. In this regard, the cooperative cloudlet-based Mobile Cloud Computing model provides possible solutions to overcome these limitations. In this cooperative model, the cloudlets cooperate with each other to fulfill user requests via WiFi connections. It also avoids the need to access the enterprise cloud through expensive technologies such as 3G and 4G, resulting in less overall consumed power in mobile devices. In a similar model, virtual data centers in cloud computing environment can cooperate to share all resources they have. In this paper, we will represent the cooperative models of a large-scale cloudlet deployment for mobile cloud computing and cooperative virtual data centers for cloud computing.
