© 2021 IFIP.Data Center Networks (DCNs) have become critical infrastructures with the enormous increase in the amount of data generated. This increase introduces some problems in DCNs such as high cabling complexity, high-level power consumption, low space utilization, and oversubscription. Wireless DCNs (WDCNs) address these problems by decreasing cabling complexity and power consumption and increasing space utilization thanks to their incorporation of wireless communication technologies. Moreover, with its highly flexible structure, WDCNs efficiently utilize the bandwidth and provide a promising solution to the oversubscription problem. However, WDCNs pose some challenges such as meeting dynamic traffic demands and increasing throughput in the data center. In this work, we propose a WDCN with dynamic topology, and we aim to handle the dynamic traffic demand of virtual machines (i.e., services) and maximize throughput by efficiently embedding virtual machines into physical machines (i.e., servers) and deploying wireless transceivers on top of the racks to establish dynamic wireless communication using unlicensed 60 GHz bands. To maximize throughput in the WDCN, we create a mixed-integer programming (MIP) problem. Due to the complexity of the problem, we also introduce two heuristics named Heuristic for Wireless Link and Service Deployment (HWSD) and Improved HWSD (I-HWSD). These heuristics significantly improve the time it takes to solve the MIP problem with an optimization solver and approach the optimal solution by about 20%. Unlike top-of-rack (ToR)-to-ToR WDCN, which doesn't consider deploying virtual machines, we increase the throughput we can achieve by deploying virtual machines according to the average traffic demands between them.

Evaluation of Terahertz Channel in Data Centers MOLLAHASANİ, Shahram; Onur, Ertan (2016-04-29) Designing data center network topologies with the objective of minimizing cost, increasing bisection bandwidth and decreasing latency is a difficult problem. The solutions in the literature mainly concentrate on wired networks and minimizing wiring costs thereof. Only a few proposals address the benefit of employing wireless communications in data centers due to spectrum and bandwidth limitations of current wireless communication technologies. By using terahertz communication in a data center as a complemen...
Joint Virtual Machine Embedding and Wireless Data Center Topology Management Bütün, Beyza; Onur, Ertan; Department of Computer Engineering (2022-5-10) With emerging technologies such as the Internet of Things and 5G, generated data grows enormously. Hence, Data Center Networks (DCNs) have an important duty to store and process a significant amount of data, which makes them a critical component of the network. To meet the massive amount of traffic demands, wired DCNs need to deploy large numbers of servers and power-hungry switches, and huge lengths of wires. An enormous increase in the usage of cables causes high cabling complexity and cost while deployin...
Optimized Multi-Constrained Quality-of-Service Multipath Routing Approach for Multimedia Sensor Networks Hasan, Mohammed Zaki; Al-Turjman, Fadi; Al-Rizzo, Hussain (2017-04-01) Modern multimedia sensor networks impose strict constraints on both the delay and energy consumption when time-critical data must be reported to the sink within a limited bandwidth without any loss. Failure to transmit an event to the sink occurs for many reasons, including inherence limitations of sensors, power consumption, and reliability. We propose a mathematical model for a novel quality-of-service (QoS) routingdetermination method. The proposed scheme enables determining the optimal path to provide a...
Joint optimization of cell zooming, scheduling and user association Çalık, Mert; Onur, Ertan; Department of Computer Engineering (2018) Capacity can be increased by employing small cells in future mobile networks. When small cells are considered, a large number of base stations have to be deployed. This approach enlarges network infrastructures and increases the amount of energy consumption. Traffic demand in a mobile network is not fixed in time or space, and it cannot be accurately predicted in advance. Network functions such as base station scheduling, cell zooming or user-to-base-station association can be dynamically controlled to cons...
TCP-Peach++: Enhancement of TCP-Peach+ for satellite IP networks with asymmetrical bandwidth and persistent fades - (Invited paper) Fang, J; Akan, OB (2005-01-01) In this paper, an improvement to TCP-Peach+, called TCPPeach++, is proposed to improve the throughput performance for satellite IP networks with asymmetrical bandwidth and persistent fades. The delayed SACK scheme is adopted to address the problems due to bandwidth asymmetrical satellite links. A new protocol procedure, Hold State, is developed to address the link outages due to persistent fades. The simulation results show that TCP-Peach++ improves the throughput performance during rain fades and addresses...
