A Mobile Edge Computing Server Deployment Scheme in Wireless Mesh Network

As a wireless network structure that can solve the “last kilometer” bottleneck of the Internet, Wireless Mesh Network (WMN) has been one of the hot topics in wireless network. However, the existing WMN is difficult to meet the future demand of delay. Mobile Edge Computing (MEC) is an emerging technology that can significantly reduce latency. With the rapid development of 5G communications and compute-intensive applications, MEC has attracted more and more attention. Combining WMN with MEC can make the WMN better meet the delay requirements of future network. In this paper, we propose a cluster scheme to deploy Mobile Edge Computing Server (MECS). We first select appropriate cluster heads as the Mesh Gateways (MGs) according to the computation tasks of the node and the number of neighbor nodes. Then cluster the WMN according to the computation capability and Hop-count constraints. The MECS is deployed in the MG to provide services for Mesh Clients (MCs) offloading computing tasks. The simulation results show that the scheme can effectively improve the performance of WMN in terms of delay.
