Network selection is a key technology to realize fair resource allocation and load balancing for converged multi-radio heterogeneous networks. In this paper, we propose a Multiple attribute decision making and Evolutionary Game Theory (MEGT) integrated network selection scheme. In MEGT, utility functions are designed appropriately to compute user QoS satisfaction of the candidate network. User preferences...
The IEEE 802.16e standard provides five different scheduling services to meet the QoS requirement of multimedia applications and this paper investigates one specific scheduling service, i.e. rtPS scheduling. In order to relieve the serious MAC overhead problem in WiMAX system, an efficient scheduling algorithm for the rtPS services has been proposed in this paper. Also the algorithm has been implemented...
In IEEE 802.16e system, most of existing scheduling algorithms focus on the real time services, while few of them have particularly considered the best-effort (BE) service. Since the BE service class is defined for non-realtime traffic with the lowest priority among all 802.16e scheduling services, it corresponds to applications with no specific rate or delay requirement. However, considering the...
