Abstract
-
The convergence of mobility, multimedia and the Internet is finally seen possible through third generation (3G) wireless systems. A key part of this evolution is Quality of Service (QoS), which is simply a set of service requirements (e.g., delay, bit error rate, guaranteed bit rate) to be met by the network while transporting traffic streams from source to destination. Essential to the notion of QoS is resource management that resolves users competition to utilize network resources according to their QoS agreements. In this thesis, we propose a novel wireless resource scheduler for controlling the transmission power and bit rate of mobile calls cooperatively while previous work has focused on handling them separately. The proposed scheme is called the Genetic Algorithm for Mobiles Equilibrium (GAME). Based on an evolutionary computational model, GAME assigns optimally both transmitting power and bit rate to every mobile station. Optimal allocation is in the sense that every user gets only enough resources necessary for meeting or exceeding its QoS requirements. Having done that, we gain further benefits as well. In addition to QoS provisioning, lower transmitting power extends a mobile station battery life and minimizes the interference seen by other users. Moreover, improved coverage efficiency reduces infrastructure cost by requiring fewer base stations per square kilometer. In short, GAME raises the number of QoS-satisfied mobile stations in a cell. Various simulations show improvements achieved over the established scheme.
