Indeed, they are a promising solution to improve coverage and to offload data traffic in mobile networks. In this paper, we propose a signaling-less architecture of the heterogeneous network composed of one single Macro Base Station and a Single Small-Cell. First, we construct a game theoretic framework for channel-state independent interaction. We present many conditions for the existence of Pure Nash equilibrium. Next, and in order to capture the continuous change of the channel state, we build a random matrix game where the channel state is considered to be random (potentially ruled by some given distribution). A characterization of Nash equilibrium is provided in terms of pure strategies and mixed strategies. Convergence to Nash equilibrium is furthermore guaranteed using a variant of the well-known Combined fully distributed payoff and strategy learning. Our algorithm converges faster (only 10-20 iterations are required to converge to Nash equilibrium) and only need a limited amount of local information. This is quite promising since it says that our scheme is almost applicable for all environments (fast fading included).}, isbn = {978-1-4799-5344-8}, issn = {2376-6492}, author = {Ben Chekroun, Samia and Sabir, Essaid and Kobbane, Abdellatif and Tembine, Hamidou and Bouyakhf, El-Houssine and Ibrahimi, Khalil} } @article {5099547320100301, title = {The Uplink Capacity Evaluation of Wireless Networks: Spectral Analysis Approach.}, journal = {Journal of Computing \& Information Technology}, volume = {18}, number = {1}, year = {2010}, pages = {1 - 17}, abstract = {In this paper we study the capacity of wireless cellular network, in particular the uplink of WCDMA system by using the two dimensional continuous-time Markov chain (CTMC) technique. Considering two types of calls: real-time (RT) calls characterized by a quasi fixed transmission rate, and best-effort (BE) calls which do not require strict demand but need some reliability conditions, we develop an approach based on the spectral analysis for evaluating the cell capacity. We explicitly obtain the simultaneous distribution of the number of RT connections and the number of BE connections in the steady-state. This analysis allows us to simplify the computation of the performance measures including expected delay and throughput of BE traffic. These performances are obtained explicitly in both cases (finite and infinite) of BE calls as function of system parameters like arrival rate of BE and RT calls, service rate of BE and RT calls. These results allow the operator to evaluate the cell capa}, keywords = {call admission control, Data transmission systems, Markov processes, Matrix-Geometric method, Mobile communication systems, spectral analysis approach, Spectrum analysis, Telecommunication systems, Wireless communication systems, wireless networks}, issn = {13301136}, url = {http://search.ebscohost.com/login.aspx?direct=true\&db=iih\&AN=50995473\&site=ehost-live}, author = {Kobbane, Abdellatif and El-Azouzi, Rachid and Ibrahimi, Khalil and Samanta, Sujit Kumar and Bouyakhf, El-Houssine} }
