With the rapid development of network technology and network services, the users' requirements of network QoS are also improved. The traditional Active Queue Management(AQM) mechanisms are not adequate to provide QoS guarantee to multimedia video traffics effectively. To provide better quality of service to the multimedia applications in Mobile Ad Hoc Network(MANETs), whose resource is limited and...
High speed downlink packet access (HSDPA) was introduced in WCDMA as an enhance technology. The objective of the major component fast packet scheduling is to ensure the fairness between users according to their instantaneous channel state. We proposed in this paper a novel packet scheduling algorithm for HSDPA which is based on QoS assurances. This algorithm is called classified wireless fair queuing...
In this paper, a novel performance analytical model, which uses discrete Markov and M/M/1/K theory, is presented for IEEE 802.11 based wireless networks with finite load. Delay and loss caused by MAC contention and buffer queuing are studied in detail. This model and analysis give an in-depth insight and understanding to the unfairness between uplink and downlink flows that are forwarded by access...
