Virtual Network Mapping Algorithm in Wireless Data Center Networks

摘要

In a wireless data center (WDC) network, link interference and node mobility may affect resource allocation. In this paper, we propose the wireless virtual network embedding algorithm based on link interference (WVNEA-LI). We model the virtual network and the physical network in a WDC. Moreover, we allocate nodes and links simultaneously based on a concurrent mechanism. According to a link interference matrix, in the paper, we carry out dynamic adjustment of link allocation to balance the coordination of nodes and links. Simulation results show that the WVNEA-LI algorithm can improve the acceptance ratio of a virtual network, raise the benefit-cost ratio, and increase efficiency of network resources.
