Current mobile phones have little resemblance to their first versions regarding their functionalities. Nowadays, mobile phones have multiple cameras, come integrated with artificial intelligence and support complex video games among other functionalities. This evolution derives from another one in computing models. From hardware computing, through Mobile Cloud Computing and now a new standard, Multi-Access Edge Computing. This new model will provide the key push in the 5th generation cellular technology. This work focus the study of one of Multi-Access Edge Computing possibilities, assistance for intensive computation using offloading techniques to nearby infrastructures. The main goal is to create a proof of concept of this scenario by developing a mobile application and an infrastructure that provides this computing service. A state of the art analys and a comparison of both computing models is made in this work. An offloading system is designed and its processes and requirements are described. It is concluded that compared to local execution and when above a certain level of computing power, the implemented system has significant performance gains when offloads and executes the code in a nearby infrastructure. Another test also proved that offloading computationally intensive tasks frees the mobile phone’s resources extending its battery life.
