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 complementary technology, the performance of the data center can be enhanced and substantial savings in cabling costs can be achieved without any throughput concession. Terahertz (THz) band can overcome bandwidth limitations and satisfy a wide range of applications from classical networking to board-to-board communication. In this paper, we evaluate the terahertz channel in data centers by considering atmospheric absorption. Based on the results, we recommend employing 190310 GHz range with a bandwidth of 120 GHz. Keeping the relative humidity level at 40% will reduce atmospheric absorption while proving a healthy environmental regime for the equipment in a data center.

Joint Virtual Machine Embedding and Wireless Data Center Topology Management
Butun, Beyza; Onur, Ertan (2021-01-01)
© 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 it...
Evaluation of priority dependent and time scheduled MAC layer protocols for ad-hoc networks
Erdeğer, İsmail; Baykal, Buyurman; Department of Electrical and Electronics Engineering (2015)
Ad-hoc networks have very unique features, such as dynamic topologies, relatively limited bandwidth and wireless signal propagation schemes, which present various challenges for wireless communication. In this thesis, control mechanisms for channel access scheduling and topology in ad-hoc networks are evaluated, which utilize the information from two-hop neighborhood to cope with the communication difficulties in ad-hoc networks. Channel assignment is one of the most important topics for ad-hoc networks. Ch...
Analysis and modeling of routing and security problems in wireless sensor networks with mathematical programming
İncebacak, Davut; Baykal, Nazife; Bıçakcı, Kemal; Department of Information Systems (2013)
Wireless Sensor Networks (WSNs) are composed of battery powered small sensor nodes with limited processing, memory and energy resources. Self organization property together with infrastructureless characteristics of WSNs make them favorable solutions for many applications. Algorithms and protocols developed for WSNs must consider the characteristics and constraints of WSNs but since battery replenishment is not possible or highly challenging for sensor nodes, one of the major concerns in designing network p...
Improving performance of network intrusion detection systems through concurrent mechanisms
Atakan, Mustafa; Şener, Cevat; Department of Computer Engineering (2003)
As the bandwidth of present networks gets larger than the past, the demand of Network Intrusion Detection Systems (NIDS) that function in real time becomes the major requirement for high-speed networks. If these systems are not fast enough to process all network traffic passing, some malicious security violations may take role using this drawback. In order to make that kind of applications schedulable, some concurrency mechanism is introduced to the general flowchart of their algorithm. The principal aim is...
SWIM : a new multicast routing algorithm for wireless networks
Akyürek, Alper Sinan; Uysal Bıyıkoğlu, Elif; Department of Electrical and Electronics Engineering (2011)
In this work, a new multicast routing algorithm for wireless networks is presented. The algorithm, called SWIM (Source-initiated WIreless Multicast), is a depth-optimal multicast tree formation algorithm. SWIM is fully distributed and has an average computational complexity of O(N 2 ). SWIM forms a shared tree from the source(s) to destinations; yet, as a by-product, it creates a multicast mesh structure by maintaining alternative paths at every tree node. This makes SWIM suitable for both ad hoc networks a...
