Sentence examples for medium access mechanisms from inspiring English sources

Since these networks rely on different medium access mechanisms, methods to estimate the link quality have to be adapted to each of them.

The CSMA medium access mechanisms that are implemented by different communication protocols differ on how the waiting time intervals before transmitting are evaluated, either after sensing the medium idle, or before re-transmitting after a collision.

To enhance the QoS support, IEEE 802.11e introduces a protocol called the HCF which includes two medium access mechanisms: contention-based channel access and controlled channel access which are referred to as the EDCA and HCCA.

Some recent work regarding provision of QoS in WLANs show the initiation of efforts regarding creation of adaptive medium access mechanisms based on IEEE 802.11e QoS propositions as an acknowledged way forward for the issue.

To realize these use cases, IDRA has built-in features that are able to cope with the following network challenges: (1) heterogeneous (legacy) devices can use different packet types, (2) heterogeneous (legacy) devices can use conflicting medium access mechanisms and (3) heterogeneous (legacy) devices can use different higher-layer network protocols.

HCCA is one of the medium access mechanisms in the IEEE 802.11 standard, and uses the polling scheme similar to the point coordination function (PCF) to provide reliable quality of service (QoS), which may cause resource overshooting and high time consuming.

The standard uses CSMA/CA medium access mechanism and supports star as well as peer-to-peer topologies.

A PU arrival rate prediction and channel holding time estimation-based medium access mechanism is presented in [18].

Therefore, an important part of this system from an efficiency point of view is the medium access mechanism.

Although its priority based medium access mechanism provides guaranteed immediate access for the highest priority messages, it may cause unpredictability in communication media for the lower priority messages.

The medium access mechanism of the IEEE 802.11 standard [1] is a CSMA with Collision Avoidance (CSMA/CA), also called Distributed Coordination Function (DCF).
