Access Characteristic-Guided Remote Swapping Across Mobile Devices

Extension of Conference Paper: This manuscript extends our UIC 2022 [29] paper. The access characteristics of the remote swapping are further studied, which should be utilized with a new design. This journal version presented a practical design to solve these issues with a significant extension to the conference work. There are three major contributions: enhanced access characteristics studied, refining the handling of system services, and network traffic-aware remote paging. We summarize the changes and new materials in this submission, as follows: 1. We added a novel network traffic-aware remote paging (NaRP) scheme to avoid the impact of network traffic on remote swapping. It monitors the network condition and performs hierarchical remote paging (Section 5). 2. We added new designs to the origin access characteristic guided remote swapping scheme through refining the handling of system services. Specifically, based on the newly discovered access characteristics, we proposed two new designs (i.e., SPS and RSP) respectively (Section 4). 3. We added new access characteristics of the applications, and more observations are made on the system service process. For example, we find that the swap-in of the system services is concentrated in several specific processes (Section 3). 4. We added the comparative analysis of the state-of-the-art method and the proposed approaches (Section 2). 5. We added the implementation details and limitation discussion (Section 6). 6. We reconducted the experiments on the latest experimental platforms (Google Pixel 6, Android 13) to demonstrate the effectiveness and advancement of our findings and designs (Sections 3 and 7). 7. The experiment evaluates improved approaches' performance and overhead (Section 7). 8. Evaluation and analysis of dynamic parameters in design are added (Section 7.5). 9. More information about the background of this work is added. Based on the above extension, we believe that there are 50% more new contributions added in this version.
