Abstract
The mobile edge computing architecture successfully solves the problem of high latency in cloud computing. However, current research focuses on computation offloading and lacks research on service caching issues. To solve the service caching problem, especially for scenarios with high mobility in the Sensor Networks environment, we study the mobility-aware service caching mechanism. Our goal is to maximize the number of users who are served by the local edge-cloud, and we need to make predictions about the user’s target location to avoid invalid service requests. First, we propose an idealized geometric model to predict the target area of a user’s movement. Since it is difficult to obtain all the data needed by the model in practical applications, we use frequent patterns to mine local moving track information. Then, by using the results of the trajectory data mining and the proposed geometric model, we make predictions about the user’s target location. Based on the prediction result and existing service cache, the service request is forwarded to the appropriate base station through the service allocation algorithm. Finally, to be able to train and predict the most popular services online, we propose a service cache selection algorithm based on back-propagation (BP) neural network. The simulation experiments show that our service cache algorithm reduces the service response time by about 13.21% on average compared to other algorithms, and increases the local service proportion by about 15.19% on average compared to the algorithm without mobility prediction.

Summary
With the rapid development of large-scale cloud computing, more and more service providers have chosen to deploy content and services on the cloud. Speaking, such services are highly delay-sensitive, and have complex computing requirements For this problem, the researchers propose a mobile edge computing model, i.e., deploying an edge-cloud server on the base station which is close to the end user to perform some computing jobs. The researchers propose a mobile edge computing model, i.e., deploying an edge-cloud server on the base station which is close to the end user to perform some computing jobs It can significantly reduce network transmission delay [4].
