Sentence examples for medium access priorities from inspiring English sources

Achary et al. in their work presented an approach that adaptively changes the contention window sizes of different traffic classes based on the medium access priorities and length of their transmission queues [15].

Table 2 gives the overall medium access priorities of the aforementioned traffic categories by positioning them in the range of 0 to 6, with 0 representing the highest and 6 representing the lowest priority.

Ambient wireless traffic is handled with modified 802.11b medium access control parameters providing the proposed system with a greater medium access priority.

Furthermore, to increase the downlink throughput, the proposed mechanism grants the access point greater medium access priority as compared to the stations for most of the traffic categories.

Each traffic category gets different medium access priority with voice getting the highest, video second highest, best effort second least and background getting the least priority to access the medium.

In Table 2, it can be seen that voice gets the highest priority with same medium access priority for access point and the stations because for voice, similar amount of traffic is present at the uplink and the downlink.

The mechanism also proffers higher medium access priority to the access point as compared to the stations in order to cope with the issue of uplink/downlink traffic asymmetry.

This medium access priority is enforced by awarding different contention window sizes to different traffic categories with highest priority traffic category getting the lowest contention window size and different sizes of arbitration inter-frame space (AIFS) with high priority traffic transmitting with shorter inter-frame space.

1. Voice: to accommodate the bursty nature of voice traffic, reduced inter-frame space (RIFS) introduced in the IEEE 802.11n standard is used by the proposed mechanism as RIFS is more suitable for traffic that has considerable inter-frame interval but require higher medium access priority [34].

The protocol betters the identified problem of EDCA, that EDCA while providing higher medium access to high priority traffic classes causes starvation for low priority traffic classes.

The first mechanism provides high-priority medium access to the current receiver to avoid intra-flow contention at each node.
