An ideal Network Processor, that is, a programmable multi-processor device must be capable of offering both the flexibility and speed required for packet processing. But current Network Processor systems generally fall short of the above benchmarks due to traffic fluctuations inherent in packet networks, and the resulting workload variation on individual pipeline stage over a period of time ultimately...
Because of bursty high data rate and delay sensitive nature of high quality multimedia application, the resource allocation in wireless network to meet its quality of service (QoS) has become the most challenging and interesting issue. Orthogonal Frequency Division Multiple Access (OFDMA) employing adaptive channel allocation technique can support these requirement while increasing the system capacity...
The next generation cellular wireless network is expected to provide a broad range of multimedia services, where the traffic asymmetry between uplink and downlink is significant. The code division multiple access system with time division duplex mode (TDD-CDMA), adopting unbalanced slot allocation between uplink and downlink, is a good solution for this traffic asymmetry. Here a QoS adaptive multimedia...
Current advances in the area of wireless access networks, and the increasing demand for real time services (e.g. video-on-demand, voice), requires, that the quality of service (QoS) guarantees in wireless networks are met, while ensuring a high level of network utilization. Call admission control (CAC) plays a significant role in providing the desired QoS in code division multiple access (CDMA) integrated...
