Analysis of Cognitive Radio Scenes Based on Non-cooperative Game Theoretical Modelling
Ligia Cremene, Dumitru Dumitrescu
A noncooperative game theoretical approach for analysing opportunistic spectrum access (OSA) in cognitive radio (CR) environments is proposed. New concepts from game theory are app…
Cognitive Radio Simultaneous Spectrum Access/ One-shot Game Modelling
Ligia C. Cremene, D. Dumitrescu, Reka Nagy +1
The aim of this work is to asses simultaneous spectrum access situations that may occur in Cognitive Radio (CR) environments. The approach is that of one shot, noncooperative games…
Game Theoretical Modelling for Dynamic Spectrum Access in TV Whitespace
Ligia C. Cremene, D. Dumitrescu, Reka Nagy +1
In order to assess TV whitespace access scenarios, three oligopoly game models are considered and reformulated in terms of radio access: Cournot, Stackelberg, and Bertrand. Besides…
Distributed Pharaoh System for Network Routing
Camelia-M. Pintea, D. Dumitrescu
In this paper it is introduced a biobjective ant algorithm for constructing low cost routing networks. The new algorithm is called the Distributed Pharaoh System (DPS). DPS is base…
Sensitive Ants in Solving the Generalized Vehicle Routing Problem
Camelia-M. Pintea, Camelia Chira, D. Dumitrescu +1
The idea of sensitivity in ant colony systems has been exploited in hybrid ant-based models with promising results for many combinatorial optimization problems. Heterogeneity is in…
New results of ant algorithms for the Linear Ordering Problem
Camelia-M. Pintea, Camelia Chira, D. Dumitrescu
Ant-based algorithms are successful tools for solving complex problems. One of these problems is the Linear Ordering Problem (LOP). The paper shows new results on some LOP instance…
