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...
In this paper, we proposed a dynamic network pricing scheme, which considers both Call Admission Control (CAC) and Network Congestion Control (NCC), denoted as Contract Binded CAC {CBCAC). CAC calculates the optimal arrival rates and limits the admitted calls at every time. When the network is underlized, all the users are charged for service consumption normally. But if it is congested, they are...
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 this paper, we propose a Call Admission Control-based dynamic pricing scheme that aims at preventing congestion and maximizing the utilization of broadband wireless access systems. The main aim of our scheme is to provide monetary incentives to users to use the wireless resources efficiently and rationally; hence, allowing efficient bandwidth management at the admission level. By dynamically determining...
While the demand for mobile broadband wireless services continues to increase, radio resources remain scarce. Even with the substantial increase in the supported bandwidth in next generation Broadband Wireless Access Systems (BWASs), it is expected that these systems will severely suffer from congestion due to the rapid increase in demand of bandwidth intensive applications. Without efficient bandwidth...
