Conference Object Citation - WoS: 6Citation - Scopus: 6A Merging Clustering Algorithm for Mobile Ad Hoc Networks(Springer Verlag, 2006) Dağdeviren, Orhan; Erciyeş, Kayhan; Erciyeş, Kayhan; Çokuslu, Deniz; Dağdeviren, Orhan; 03.04. Department of Computer Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyClustering is a widely used approach to ease implementation of various problems such as routing and resource management in mobile ad hoc networks (MANET)s. We propose a new fully distributed algorithm for clustering in MANETs that merges clusters to form higher level clusters by increasing their levels. We show the operation of the algorithm and analyze its time and message complexities and provide results in the simulation environment of ns2. Our results conform that the algorithm proposed is scalable and has a lower time and message complexities than the other algorithmsConference Object Citation - WoS: 2Citation - Scopus: 2Performance and Complexity Analysis of Suboptimal Mimo Detectors(Institute of Electrical and Electronics Engineers Inc., 2005) Özbek, Berna; Özbek, Berna; 03.05. Department of Electrical and Electronics Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyIn this paper, we consider coded MIMO systems using suboptimal iterative receivers. We propose to use the list type breadth first detectors based on M and TM algorithms and the soft output linear MMSE detectors with a priori information. We compare these two families of suboptimal iterative receivers in terms of complexity and bit-error-rate performance.Conference Object Citation - WoS: 3Citation - Scopus: 6Approximate Stationary Density of the Nonlinear Dynamical Systems Excited With White Noise(Institute of Electrical and Electronics Engineers Inc., 2005) Günel, Serkan; Savacı, Ferit Acar; Savacı, Ferit Acar; 03.05. Department of Electrical and Electronics Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyIn this paper, obtaining approximate solution of Fokker-Planck-Kolmogorov (FPK) Equation using compactly supported functions has been discussed. With specific choice of such functions as piecewise multivariable polynomials which are supported on ellipsoidal regions, the parameters to be determined can be considerably decreased compared to Multi- Gaussian Closure scheme [1]. An example commonly considered in the literature has been analyzed and the proposed method has been compared with the Multi-Gaussian Closure scheme. The simulation results indicate that the new scheme is quite successful even if the driving noise is not white Gaussian, but has an exponential correlation function with small correlation time.
