Quality of service based media access control for mobile ad hoc networks

摘要

A manager node ( 105 ) controls access to a shared network communication medium by a number of nodes. A first node ( 101 ) transmits a request to the manager node ( 105 ). The request includes information indicating that the first node ( 101 ) requires a QoS link to a second node. The manager node ( 105 ) determines whether the QoS link from the first node ( 101 ) to the second node can be supported and sends an accept message to the first node ( 101 ) when the QoS link can be supported. Prioritized media access control may also be used in a distributed network without using a manager node to control access to a shared communication medium. A node with high priority data may reduce the duration of its contention window so that it will have a better chance of gaining control of the shared communication medium than a node with low priority data.
