This is the era of mobile devices, there are so many mobile applications and the number of advanced applications are increasing too fast in the market. Mobile devices are resource constrained, so it is very difficult to run many of these mobile applications simultaneously due to complex processing tasks. For this complication, we need mobile cloud computing (MCC), in which resources based on cloud are used to increase the capabilities of mobile devices in terms of computing. In this paper, we are surveying how the tasks can be uploaded on cloud server by mobile devices, task allocation in distributed wireless networks, how to protect location privacy for task allocation, how to reduce the communication cost and how to assure quality of services (QoS). The main aim is to determine in which cloud server to upload the task and how to upload the task by which task response time will be reduced. In this paper, we are comparing some algorithms, in which the task response time should be minimal, in which we can reduce the communication delay to upload a task. © 2016, International Journal of Pharmacy and Technology.
