Power control is an important component of the resource management strategy in wireless networks to achieve higher utilization and/or better quality of service. In this paper, we present a framework of decentralized power control called trajectory-based power control (TBPC), by setting the SIR target of each wireless station according to some trajectory, which is specified to reflect the corresponding...
A handoff scheme based on guard channel, queuing and channel preemption (GCQCP) is proposed to guarantee the QoS of handoff traffic in the heterogeneous hierarchical wireless networks. On the basis of bidirectional call-overflow between different networks, guard channels are set for real-time traffic handoffs and buffer queues are set for nonreal-time traffic handoffs. In order to further decrease...
