Flow control is an important means of avoiding congestion and providing QoS guarantee in networks. In this paper, a differentiated pricing scheme for flow control in General Multiuser Access Networks (GMAN) is proposed. Under this scheme, the problem of optimizing the network performance is formulated as a two-level hierarchical network game. By employing the Gerolamo Cardano Formula, we obtain the...
Next generation wireless systems represent an heterogeneous environment encompassing different radio access network technologies (RATs) that differ in bandwidth, latency or cost. At the same time, mobile devices can now support multiple radio network interfaces and are therefore able to select from various available multiple heterogeneous access networks the most appropriate one in order to satisfy...
Pricing can be an effective way to improve system utilization and performance, which can help service providers maximize their profit. The future network will be heterogeneous, so new pricing mechanisms should be proposed which take the characters of the competitive heterogeneous network into consideration. To achieve this, firstly a reasonable utility model is given, which considers factors like...
Supporting the diverse QoS requirements of multimedia applications is an essential requirement for broadband wireless access (BWA) networks. Due to the projected dynamics in traffic patterns, more capable resource management functionalities are needed. We propose a game-theoretic, congestion-based pricing scheduler that incorporates two sub-schemes: a bandwidth provisioning sub-scheme to address the...
In 3G wireless technologies, competitive operators are assigned a fixed part of the spectrum from long-term auctions. This is known to lead to utilization inefficiencies because some providers can be congested while others are lightly used. Moreover it forbids the entrance of new candidate providers. There is now a stream of work dealing with spectrum sharing among providers to lead to a better utilization...
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...
