Motivated by the specific characteristics of mmWave technologies, we discuss the possibility of an authorization regime that allows spectrum sharing between multiple operators, also referred to as spectrum pooling. In particular, considering user rate as the performance measure, we assess the benefit of coordination among networks of different operators, study the impact of beamforming at both base stations and user terminals, and analyze the pooling performance at different frequency carriers. We also discuss the enabling spectrum mechanisms, architectures, and protocols required to make spectrum pooling work in real networks. Our initial results show that, from a technical perspective, spectrum pooling at mmWave has the potential to use the resources more efficiently than traditional exclusive spectrum allocation to a single operator. However, further studies are needed in order to reach a thorough understanding of this matter, and we hope that this article will help stimulate further research in this area.


Utility analysis and computer simulation of RFID technologies in the supply chain applications of production systems
Bolatlı, Yurtseven; Eren, Pekin Erhan; Department of Information Systems (2009)
In this thesis, the feasibility of deploying RFID technologies in the case of “lowvolume high-value” products is considered by focusing on the production processes of a real company. First, the processes of the company are examined and associated problems are determined. Accordingly, a simulation of the current situation is constructed by using the discrete event simulation technique, in order to obtain an accurate model. In addition to modeling the current situation, this simulation model provides a flexib...
Immune system based distributed node and rate selection in wireless sensor networks
Atakan, Baris; Akan, Ozguer B. (2006-12-13)
Wireless sensor networks (WSNs) are event-based systems that rely on the collective effort of dense deployed sensor nodes. Due to the dense deployment, since sensor observations are spatially correlated with respect to spatial location of sensor nodes, it may not be necessary for every sensor node to transmit its data. Therefore, due to the resource constraints of sensor nodes it is needed to select the minimum number of sensor nodes to transmit the data to the sink. Furthermore, to achieve the application-...
Network-wide energy efficiency in wireless networks with multiple access points
Ozel, Omur; Uysal, Elif (2013-10-01)
This paper presents a distributed mechanism for improving the overall energy efficiency of a wireless network where users can control their uplink transmit power targeted to the multiple access points in the network. This mechanism lets the network achieve a trade-off between energy efficiency and spectral efficiency through the use of suitably designed utility functions. A user's utility is a function of throughput and average transmission power. Throughput is assumed to be a sigmoidal function of signal-t...
Cognitive Radio Sensor Networks
Akan, Ozgur B.; Karli, Osman B.; Ergul, Ozgur (2009-07-01)
Dynamic spectrum access stands as a promising and spectrum-efficient communication ion approach for resource-constrained multihop wireless sensor networks due to their event-driven communication nature, which generally yields bursty traffic depending on the event characteristics. In addition, opportunistic spectrum access may also help realize the deployment of multiple overlaid sensor networks, and eliminate collision and excessive contention delay incurred by dense node deployment. Incorporating cognitive...

Feedback control systems, of which control loops are closed over a real-time communication network, are called Networked Control Systems (NCSs). In this study the message scheduling problem for NCSs with time slotted communication protocols is tackled First, an algorithmic approach is presented to check the necessary and sufficient conditions for a given message schedule such that the real-time requirements of the system are satisfied Second, starting from an initial schedule, Simulated Annealing is used to...
