Advances in the wireless cellular and network applications also necessitate increased traffic on the communications infrastructure. In order to overcome the capacity overload of the current spectral provisions, service providers are looking at higher frequencies. E and V bands of the millimetre wave spectrum are being utilized for mile range relay links, and higher frequency bands such as 220GHz and 340 GHz regions are being considered for indoor very high data rate applications [1]. A major conundrum in front of indoor Terahertz wireless networking is the effect of the surface reflection: which may be a positive in terms of wider area coverage, and also may be a handicap due to low penetration depths through doors, panels, and such. Indoor surfaces have many different types and textures, and a parameter which may well alter surface reflection coefficients is the varying temperature. Indoor temperature variations are not extreme as the outdoor conditions, yet differentials in excess of 15° to 20° Celcius are normal for most climates throughout seasons. In this work the effect of the varying temperature surface reflections on the communication signal quality of very high data rate (>1Gb/s) data carrying indoor millimetre wave (>100GHz) transmission is studied. It is observed that data transmission quality is more easily affected by the temperature dependant surface reflections compared to conventional reflection power measurements. Various surfaces such as clear and coated drywall, wood panelling, and plastic materials are investigated. In future work, texture roughness and temperature variation will be explored.

GreenSlice: An Energy-Efficient Secure Network Slicing Framework Akin, Ozan; Gulmez, Umut Can; Sazak, Ozan; Yagmur, Osman Ufuk; Angın, Pelin (2022-02-01) The fifth generation of telecommunication networks comes with various use cases such as Enhanced Mobile Broadband, Ultra-Reliable and Low Latency Communications and Massive Machine Type Communications. These different types of communications have diverse requirements that need to be satisfied while they utilize the same physical infrastructure. By leveraging Software Defined Network (SDN) and Virtual Network Function (VNF) technologies, the 5G network slicing concept can provide end-to-end logical networks ...
Modulation formats for wavelength division multiplexing (WDM) systems Büyükşahin Öncel, F. Feza; Çakır, Serhat; Department of Physics (2009) Optical communication networks are becoming the backbone of both national and international telecommunication networks. With the progress of optical communication systems, and the constraints brought by WDM transmissions and increased bit rates, new ways to convert the binary data signal on the optical carrier have been proposed. There are different factors that should be considered for the right choice of modulation format, such as information spectral density (ISD), power margin, and tolerance against gro...
Multimedia communication in wireless sensor networks Gurses, E; Akan, OB (2005-07-01) The technological advances in Micro ElectroMechanical Systems (MEMS) and wireless communications have enabled the realization of wireless sensor networks (WSN) comprised of large number of low-cost, low-power multifunctional sensor nodes. These tiny sensor nodes communicate in short distances and collaboratively work toward fulfilling the application specific objectives of WSN. However, realization of wide range of envisioned WSN applications necessitates effective communication protocols which can address ...
Performance evaluation of routing protocols in wireless ad hoc networks with service differentiation Yılmaz, Semra; Koçyiğit, Altan; Erten, Murat; Department of Information Systems (2003) An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any fixed network infrastructure or centralized administration. Due to the limitations in the wireless environment, it may be necessary for one mobile host to enlist the aid of other hosts in forwarding a packet to its destination. In order to enable communication within the network, a routing protocol is needed to discover routes between nodes. The primary goal of ad hoc network routing pro...
Mobile multi-access IP: a proposal for mobile multi-access management in future wireless IP networks Altuntas, S; Baykal, Buyurman (Elsevier BV, 2005-03-15) As the wireless networking technologies advance rapidly, providing mobile users with roaming freely in heterogeneous wireless access domains, the need for multi-access arises. This paper introduces the Mobile Multi-Access Management Architecture (MMA-IP) for IP-based future wireless networks. MMA-IP enables mobile users to utilize multiple access domains synchronously and to switch between different access domains. In order to handle multi-access operations, MMA-IP defines a new special mobility agent, call...
