A novel perception-based data hiding technique for digital audio is proposed. It exploits the
lower sensitivity of the human auditory system (HAS) to phase distortion in audio compared …

A hybrid overlay/underlay cognitive radio network (CRN) is demonstrated to provide high
spectrum efficiency and channel capacity. Decision‐making in joining CRNs is one of the …

The increasing demand for advanced services in wireless networks raises the problem for
quality of service (QoS) provisioning with proper resource management. In this research …

The subscription of cellular networks is continuing to experience a growth at an
unprecedented rate. It becomes a significant challenge for the cellular service provider to …

The call admission control (CAC) optimizes the use of allocated channels against offered
traffic maintaining the required quality of service (QoS). Provisioning QoS to user at cell …

Generally, the wireless network provides priority to handover calls instead of new calls to
maintain its quality of service (QoS). Because of this QoS provisioning, a call admission …

The call admission control (CAC) optimizes the use of allocated channels against offered
