Integrated femtocell/macrocell networks, comprising a conventional cellular network overlaid with femtocells, offer an economically appealing way to improve coverage, quality of service, and access network capacity. The key element to successful femtocells/macrocell integration lies in its selforganizing capability. Provisioning of quality of service is the main technical challenge of the femtocell/macrocell integrated networks, while the main administrative challenge is the choice of the proper evolutionary path from the existing macrocellular networks to the integrated network.In this paper, we propose a new Autonomic Architecture with self organizing capabilities based on the election of a Femtocell cluster Head (FH) for each group of Femtocell APs. The FH will be responsible to dynamically adjust the network overall coverage to save FAP energy and provide better QoS to users. Further it uses an advanced decision algorithm for intelligent handovers.

The previous studies have shown that the gas adsorption process in a microporous solid is due to three phenomena: the direct adsorption (transportation phenomenon), the diffusion, and the fluctuations of the energy and the adsorbed matter quantity. These studies assume that the links between the different fluctuations are constant. In this article, we propose a new model of theses links based on the probabilistic-statistical properties of correlations and on the micropore filling theory. Currently, there is no result leading to the establishment of the general form of the correlation which is based essentially on the existing general theory of the actual statistical probability, the experiment and the scientific logic. A good agreement between the theoretical results and the measurements is obtained, which confirms the efficiency of the proposed model.
