Multimedia Mobile Cloud Computing: Application models for performance enhancement

摘要

Central to the vision of Smart City is the realization of efficient models that are capable of handling massive amounts of mobile multimedia data in the city's eco-system. Despite the improvement in hardware of mobile devices, challenges associated with analyzing, managing, and sharing of data still exist. As such, the responsiveness to real time applications and bandwidth and wireless constraints cannot be achieved by hardware design only. Therefore, there is a move towards the software side that is enabled by Mobile Cloud Computing to overcome these challenges, whereby parts of mobile applications are executed in remote servers with rich computational resources. This technology decreases the load on mobile devices and increases their performance. Several models have been proposed to increase mobile devices performance. This paper explores these models and compares them based on several performance parameters, including computation offloading, latency, bandwidth, and response time.
