The advancements of Information and Communications Technologies (ICT) have contributed to an explosive growth of high-volume, high-velocity and high-variety information assets, and the era of Big Data has emerged. The infrastructure-based networks are becoming increasingly overloaded, while the cost of maintaining and expanding the infrastructure to accommodate the Big Data communications remains...
This paper proposes a delay-aware resource provisioning policy for virtualized wireless networks (VWNs) to minimize the total average transmit power while holding the minimum required average rate of each slice and maximum average packet transmission delay for each user. The proposed cross-layer optimization problem is inherently non-convex and has high computational complexity. To develop an efficient...

Almost Blank Subframes (ABSs) are an important part of enhanced Inter-Cell Interference Coordination in 3GPP standard. The concept of ABS is to blank some subframes of macro base stations (MBSs), therefore, PBSs can have no interference from MBSs during these periods. In this work, we propose Multi-tone ABS to enhance ABS, which is referred to single-tone since only two choices can be applied on each...
One of the dominant approaches in coping with the intermittent connectivity of opportunistic networks is packet replication. However, the need for a distributed operation forces the nodes carrying a message copy to make replication decisions without taking into account the replication state of other nodes. This strategy can lead to the creation of an excessive number of replicas thus exhausting the...
Traditional fixed pricing mode limits the accepted number of users and traffic flows in networks. This results in low profits for operators. By applying appropriate pricing strategies, wireless radio resources can be utilized more adequately, and promising improvement of operation profits can be achieved. In this paper, a dynamic pricing strategy for delay tolerant service aggregation multicast in...
Wired and wireless network delays highly degrade the control performance of hybrid networked control systems(HNCS). In order to effectively restrain impact of network delay for the HNCS, a novel approach is proposed that new Smith predictor combined with fuzzy radial basis function neural network (FRBFNN), and comes true delay compensations. Because new Smith predictor does not include network delay...
