This paper proposed a mobile edge computing (MEC)‐based point of interests (POIs) downloading and proximate sharing system for a group of people, who belong to the same mobile social networks in proximity (MSN‐P) and whose handheld devices are connected in a tree‐like structure. Using the proposed system, the root handheld device plays the role of an MEC server and is charge of downloading POIs' contents from the remote cloud server using 4G/5G cellular network and then forwarding POIs' contents to other group members' handheld devices using device‐to‐device (D2D) communication. Since the number of connected handheld devices in each handheld device is limited using D2D communication, this work proposed a control scheme called k‐Connection‐Limited and n‐Hop (kCL‐nH) tree topology's construction scheme to achieve the proximate sharing of POIs' contents. Additionally, since the root handheld device consumes more battery power than others, this work proposed a control scheme that has each group member's handheld device to be the root handheld device alternatively. A credit scheme was thus proposed to denote each handheld device's contribution, which is referred for the selecting of the next root handheld device, to achieve the fairness concern. Then, the control scheme, which is executed in the corresponding MEC server, considering both remaining battery power and credit for the switching of the root handheld device was designed. The proposed method was developed using Wi‐Fi Direct over the iOS system. Experimental results have shown some interested results among power consumption, downloaded data volume and fairness among all handheld devices.

使用考虑信用的移动边缘计算服务器切换控制方案进行地理数据的邻近共享

本文提出了一种基于移动边缘计算 (MEC) 的兴趣点 (POI) 下载和邻近共享系统，适用于属于同一邻近移动社交网络 (MSN-P) 且其手持设备已连接的一群人。在树状结构中。使用所提出的系统，根手持设备扮演 MEC 服务器的角色，负责使用 4G/5G 蜂窝网络从远程云服务器下载 POI 的内容，然后使用设备将 POI 的内容转发到其他组成员的手持设备到设备 (D2D) 通信。由于每个手持设备中连接的手持设备的数量使用 D2D 通信是有限的，这项工作提出了一种称为 k-Connection-Limited 和 n-Hop (kCL-nH) 树拓扑的控制方案' 构建方案，实现兴趣点内容的就近共享。此外，由于根手持设备比其他手持设备消耗更多的电池电量，这项工作提出了一种控制方案，让每个组成员的手持设备交替成为根手持设备。因此提出了一种信用方案来表示每个手持设备的贡献，用于选择下一个根手持设备，以实现公平关注。然后，设计了在相应的 MEC 服务器中执行的控制方案，同时考虑了剩余电池电量和根手持设备切换的信用。所提出的方法是在 iOS 系统上使用 Wi-Fi Direct 开发的。实验结果显示了功耗之间的一些有趣结果，
