In this paper, we consider the joint problem of congestion control and scheduling with multi-class Quality of Service (QoS) requirements. Generally, the joint problem is formulated as a Network Utility Maximization (NUM) problem and can be decomposed into a congestion control problem and a scheduling problem. Usually, the congestion control problem can be solved in a distributed manner by tracking...
There is a need for military and commercial wireless radio networks that can operate in dynamic environments while supporting high spectral efficiency with throughput guarantees and low latency. This is particularly challenging in wireless mobile ad-hoc networks (MANET). Multiuser detection (MUD) technology promises to address these needs. But most research in MUD technology to date has focused on...
For the particular environment of pervasive grid, this paper proposed an architecture to support the access of mobile devices, introduced the accessing process and discussed the method that mobile devices was found and managed as a resource, finally in the basic of the existing grid schedule algorithm, we improved an QoS-Min-Min algorithm with the basic of the existing grid schedule algorithm so that...
In this paper, we investigate the problem of providing QoS to end-to-end flows in multihop ad hoc networks with channel errors through packet scheduling. Each flow is associated with some QoS requirement, which is requested and granted in the form of a desired service rate. The achieved rate is estimated at the destination and fed back to the source periodically. Both the desired rate and achieved...
