Bio-Inspired Nanonetworks and ICT-Inspired Neuro-Treatment

The human body is a communication network of nanonetworks composed of billions of nanomachines, i.e., cells, whose functionalities depend on molecular communications.

 

We aim to model the molecular communication channels of nervous nanonetwork, i.e., the most advanced human body system, analyze its communication theoretical capabilities, and contribute to the development of bio-inspired solutions for nanonetworks and ICT-inspired solutions for neural diseases.

TeraFemto: Terahertz Femtocell for 5G Mobile Networks

The main purpose of the project “TeraFemto- Terahertz Femtocell for 5G Mobile Networks” is to develop communication techniques for mobile communication in the frequency range above 275 GHz, which is yet to be allocated for active services by ITU. Ultimate goal of the project is to realize a communication system, which operates on low THz band with femtocell network architecture for the first time in the world. More information

 

 

Nano-scale and Quantum Communications

Nano communications is an emerging interdisciplinary research area, which aims to enable communication among nanodevices and/or over channels with nanoscale dimensions.

 

We perform cutting-edge research in communication and information theoretical modeling, analysis, and design of physically realizable communication techniques for nanodevices and nanoscale communication channels.

Cognitive Radio Sensor Networks

Cognitive radio sensor network (CRSN) can be defined as a distributed network of wireless cognitive radio sensor nodes, which sense event signals and collaboratively communicate their readings dynamically over available spectrum bands in a multi-hop manner.

 

We develop novel communication techniques to integrate cognitive radio and sensor networks, and analyze information theoretical aspects of spectrum management and event sensing in CRSN. More information

 

Mobile Ad Hoc beyond-Line-of-Sight (b-LoS) Networks

Evaporation ducts, the layer in which rapid decrease in the refractive index occurs, can be used as communication medium in maritime and coastal environments for b-LoS communications. Since the propagating signals at microwave frequencies are trapped between ducting layer and sea surface due to the rapid change in the refractive index, the signal spreading through atmosphere becomes considerably less.

 

We will develop channel model for evaporation duct based b-LoS communications. Advanced communication techniques will be introduced in order to improve the system against multipath effect. More information

Underwater Acoustic and Magneto-inductive Communications

Underwater acoustic communication (UAC) is characterized by attenuation, time-varying multipath fading, and low speed of sound. Magnetic induction (MI) method stands as a strong alternative for underwater networks due to its independence of impairments sustained by UAC.

 

We investigate information theoretical aspects of avant-garde cognitive communication techniques for UAC. On the other hand, MI can yield networking solutions which may exploit low-cost, easily-deployable and flexible antenna structures. More information

 

Broadband Wireless Communications

Today's internet will not be sufficient to handle increasing demand and quality of service in the near future. Connectivity and multimedia services will become main concerns. This mandates efficient use of wireless technologies. Next generation wireless and broadband communications aims to develop communication techniques suitable for this demand.

 

We focus on development and analysis of next generation wireless systems which are robust for roaming and suitable for multimedia applications. More information

 

Energy Efficient Scheduling for LTE

Development of cellular technologies causes more power demand for such devices. As a consequence, there is a need for new mechanisms to be adopted in order to reduce battery usage of these mobile devices.

 

We focus on identifying and adopting operational configurations that will minimize power consumption while sustaining optimal QoS for users. Examining the traffic pattern of top used mobile applications, we aim to analytically formulate the problem of optimal scheduling for LTE and solve this optimization problem. More information

 

 

Green Visible Light Communications (gVLC)

The widespread usage of wireless technology makes it an important part of total consumption. Therefore, the need for greener solutions for wireless technologies has emerged.

 

We propose using visible light communication (VLC) as a greener solution for indoor environments. VLC is preferable, since visible light part of the electromagnetic spectrum is still unregulated, and the power consumed for processing visible light is lower than its RF counterpart. We plan to design and produce an optimum communication system consuming minimum energy using visible light. More information
