For establishing communication infrastructures in the aftermath of man-made or natural disasters, ad hoc networking architectures seem to be more adequate. There are various simulators for studying ad hoc networks. However, simulators cannot accurately model all the factors of the physical environment. By using a test-bed, the significant gap between simulations and real-life implementations can be reduced. In this work, an ad hoc indoor testbed has been developed using software-defined radios (SDR). By using SDRs, we can bring reconfigurability and flexibility to our system. In order to develop and implement the physical and link layers, GNU Radio blocks are used. By abstracting the link-layer details through a virtual Ethernet interface, any legacy application can be run on the developed testbed. As an example, an open-source implementation of the optimized link state routing (OLSR) protocol and Babel routing protocol are used at the network layer in our experiments. We made the ad hoc networking testbed highly-redefinable by employing SDR and legacy software that could run on any legacy operating system or hardware. We report extensive evaluation results of the developed testbed.

A GIS-based software for lifeline reliability analysis under seismic hazard
Kestel, Sevtap Ayşe; ODUNCUOĞLU, Lütfi (2012-05-01)
Lifelines are vital networks, and it is important that those networks are still functional after major natural disasters such as earthquakes. Assessing reliability of lifelines requires spatial analysis of lifelines with respect to a given earthquake hazard map. In this paper, a GIS-based software for the spatial assessment of lifeline reliability which is developed by using GeoTools environment is presented. The developed GIS-based software imports seismic hazard and lifeline network layers and then create...
Implementation and evaluation of a synchronous time-slotted medium access protocol for networked industrial embedded systems
Gözcü, Ahmet Korhan; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2011)
Dynamic Distributed Dependable Real-time Industrial communication Protocol family (D3RIP), has been proposed in the literature considering the periodic or event-based traffic characteristics of the industrial communication networks. D3RIP framework consists of two protocol families: Interface Layer (IL) protocol family, which is responsible for providing the accurate time-division multiple access (TDMA) on top of a shared-medium broadcast channel, and Coordination Layer (CL), which is defined to fulfill the...
Software tool development for the automated configuration of flexray networks for in vehicle communication
Öztürk, Can; Schmidt, Şenan Ece; Schmidt, Klaus Werner; Department of Electrical and Electronics Engineering (2013)
The increasing use of electronic components in today’s automobiles demands more powerful in-vehicle network communication protocols. FlexRay protocol, which is expected to be the de-facto standard in the near future, is a deterministic, fault tolerant and fast protocol designed for in vehicle communication. For proper operation of a FlexRay network the communication schedule needs to be computed and the nodes need to be configured before startup. Current software tools that are geared towards FlexRay only d...
A Model Predictive Control for Microgrids Considering Battery Aging
Yilmaz, Ugur Can; SEZGİN, MUSTAFA ERDEM; Göl, Murat (2020-03-01)
The increasing number of distributed energy resources (DERs), advancing communication and computation technologies, and reliability concerns of the customers have caused an intense interest in the concept of microgrid. Although DERs are the biggest motivation of the microgrids due to their intermittent generation characteristics, they constitute a risk for system reliability. Battery storage systems (BSSs) stand as one of the most effective solutions for this reliability problem. However, the inappropriate ...
A novel receiver architecture for single carrier noma transmission in wideband sparse mimo channel.
Halil, Bura; Güvensen, Gökhan Muzaffer; Department of Electrical and Electronics Engineering (2019)
In contemporary wireless communication systems, it became necessary to provide better solutions than current communication standards because of the increasing demand for massive connectivity and throughput. Non-Orthogonal Multiple Access (NOMA) has become one of the promising candidates for fifth generation (5G) communication networks. In this thesis, Sparse Code Multiple Access (SCMA) is utilized as a single carrier NOMA technique. SCMA is a transmission protocol, in which multiple users shares same time s...
