In this paper, we investigate the effects of pricing incentives in order to control the number of users requested access in cellular system. The system has been modeled as continuous time Markov chains with Poisson traffic for both new and handover calls. With mathematical results, formulations have been derived to show the values of new call blocking probability, probability of new calls are given...
In multiservice wireless networks, Call Admission Control (CAC) is essential to assure the quality of service requirements of the supported traffic. Call requests are usually classified into two different types: narrow-band and wide-band calls. In this paper, the probabilistic CAC scheme employed is extended through a game theoretic framework for resource allocation and price bargaining for the required...
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 non-cooperative 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...
Next generation wireless networks (NGWN) will be heterogeneous, comprising a number of radio access technologies (RATs) coexisting in the same geographical area. In NGWN, a joint call admission control (JCAC) algorithm is needed to select the most appropriate RAT for each incoming call. The JCAC algorithm must be user-centric (i.e., consider user preferences in making RAT selection decisions) in order...
This paper presents an adaptive scheduling and CAC model for the revenue maximization. The algorithm shares limited resources to different traffic flows in a fair way, and at the same time it maximizes the revenue of the service provider. Used algorithm is derived from the linear type of revenue target function, and closed form globally optimal formula is presented. The method is computationally inexpensive,...
As the number of wireless network providers is constantly growing, the competition among them is about to increase as well. In future environments, where many wireless providers will be present as is the case of hotspot areas, it is realistic to assume that the subscription will be session-oriented, meaning that the users may start one session in one provider and another session in a different provider...
