In this work, a two-tier heterogeneous network is studied. Both base stations and end-devices are capable of caching. A suboptimal cache placement algorithm is proposed for lower delays assuming a statistical mobility model. The results are compared with a lower bound, the effects of the number of base stations and cache capacities are investigated, and the tradeoff between network load ratio and delay is shown.

Differential network coding in wireless networks Telsiz aǧlarda farksal aǧ kodlamasi Özdemir, Özgür; Yılmaz, Ali Özgür (2009-10-29) In this paper a three-terminal communication scenario where two users exchange information by employing differential binary modulation and network coding via a relay is considered. The transmission is divided into three slots in time where the first and second slots are allocated to the transmission of differential encoded data of the users. After demodulation, the relay broadcasts the bit-wise XOR-ed and differential encoded packet to the users in the third slot. The optimum detector and a simplified decis...
Inference of large-scale networks via statistical approaches Ayyıldız Demirci, Ezgi; Purutçuoğlu Gazi, Vilda; Department of Statistics (2019) In system biology, the interactions between components such as genes, proteins, can be represented by a network. To understand the molecular mechanism of complex biological systems, construction of their networks plays a crucial role. However, estimation of these networks is a challenging problem because of their high dimensional and sparse structures. The Gaussian graphical model (GGM) is widely used approach to construct the undirected networks. GGM define the interactions between species by using the con...
Distributed Power Control Using Non-monotonic Reaction Curves Ozel, Omur; Uysal, Elif (2009-05-15) In this paper, we study distributed power control in an interference network. In particular, distributed power control mechanisms are devised by exploiting a one-shot noncooperative game based on a suitably chosen utility function. The utility is a function of quality of service (QoS) objectives defined in terms of fading-induced outage probabilities. Equilibrium analysis of the resulting power control game is made, and its relationship with admission control is discussed. The main contribution of the paper...
Inference of switching networks by using a piecewise linear formulation Akçay, Didem; Öktem, Hakan; Department of Scientific Computing (2005) Inference of regulatory networks has received attention of researchers from many fields. The challenge offered by this problem is its being a typical modeling problem under insufficient information about the process. Hence, we need to derive the apriori unavailable information from the empirical observations. Modeling by inference consists of selecting or defining the most appropriate model structure and inferring the parameters. An appropriate model structure should have the following properties. The model...
FUZZY PREDICTION STRATEGIES FOR GENE-ENVIRONMENT NETWORKS - FUZZY REGRESSION ANALYSIS FOR TWO-MODAL REGULATORY SYSTEMS Kropat, Erik; Ozmen, Ayse; Weber, Gerhard Wilhelm; Meyer-Nieberg, Silja; DEFTERLİ, ÖZLEM (2016-04-01) Target-environment networks provide a conceptual framework for the analysis and prediction of complex regulatory systems such as genetic networks, eco-finance networks or sensor-target assignments. These evolving networks consist of two major groups of entities that are interacting by unknown relationships. The structure and dynamics of the hidden regulatory system have to be revealed from uncertain measurement data. In this paper, the concept of fuzzy target-environment networks is introduced and various f...
