Asymptotic behavior of ultra-dense cellular networks and its economic impact
, 2014
"... Abstract—This paper investigates the relationship between base station (BS) density and average rate in downlink cellular networks. This relationship has been well known for sparse de-ployment, i.e. when the number of base stations is low compared to the number of users, showing average rate is inde ..."

Jigsaw: Solving the puzzle of enterprise 802.11 analysis
- In SIGCOMM
, 2006
"... The combination of unlicensed spectrum, cheap wireless interfaces and the inherent convenience of untethered computing have made 802.11-based networks ubiquitous in the enterprise. Modern universities, corporate campuses and government offices routinely deploy scores of access points to blanket thei ..."

Optimizing Femtocell Densities for Spectrum Allocation in Cellular Networks
"... Abstract—In this work we analyze a spectrum allocation problem between two classes of users. We study the problem from the perspective of a cellular network with an underlaid femtocell network. Femtocells are deployed by the end-user, and thus the topology of femtocell networks is highly dynamic and ..."

and stochastic in nature. One way of managing the interference is to control the population size of the network. By fixing the spectrum resources available to the femtocell network, an optimal density of femtocells can be found that maximizes the performance of the network in terms of the achievable sum rate. I.
Downlink Spectrum Allocation in 5G HetNets
"... Abstract-Fifth generation mobile systems (5G) target an Average Area Spectral Efficiency (AASE) over hundred Gbps/km 2 /user for future mobile systems with an Energy Dissipation (ED) per unit area similar to the current ED levels. Heterogeneous networks (HetNets) with high density of deployed small ..."

small cells are currently adopted to aid in achieving the target ED and AASE by 5G. Limited spectrum availability requires efforts to manage the spectrum utilization in such dense deployments. Development of new network architectures and Radio Resources Management (RRM) schemes is important to address
Multiplexing, Passive Optical Network, wavelength assignment.
"... Abstract—We explore a new wavelength management for ultra-dense WDM-PONs with randomly distributed ONU wavelengths, controlled with limited thermal tunability. Static and dynamic wavelength assignment paradigms and heuristic assignment schemes for spectrum management are proposed, simulated and comp ..."

A wavelet approach to wideband spectrum sensing for cognitive radios
- in Proc. 1st Int. Conf. on Cognitive Radio Oriented Wireless Networks & Coms. (CROWNCOM), Mykonos
, 2006
"... Abstract — In cognitive radio networks, the first cognitive task preceding any form of dynamic spectrum management is the sensing and identification of spectrum holes in wireless environments. This paper develops a wavelet approach to efficient spectrum sensing of wideband channels. The signal spect ..."

, 2014
"... Abstract-Ultra dense small cell deployments and a very large number of applications are expected to be the essential aspects of the newly emerging 5 th generation (5G) wireless communication system. To match the diverse quality of service requirements imposed by a variety of applications, dynamic T ..."

The results show that dynamic TDD is indeed a very promising option for 5G networks, and substantially decreases packet outage delays. We
Fifth Generation Cellular Networks

Bandwidth-efficient management of DHT routing tables
, 2005
"... Today an application developer using a distributed hash table (DHT) with n nodes must choose a DHT protocol from the spectrum between O(1) lookup protocols [9, 18] and O(log n) protocols [20–23,25,26]. O(1) protocols achieve low latency lookups on small or low-churn networks because lookups take onl ..."
