Hop-based priority technique using 802.11e for multimedia streaming

Multimedia streaming is a key service provided by certain home appliances. Multimedia streaming services require sufficient bandwidth and delay variation to achieve good quality of service (QoS). Previous wireless ad hoc networks could not satisfy these requirements. Therefore, we propose a hop-based priority (HBP) technique using 802.11e for ensuring a good QoS of a multimedia streaming service. Multimedia streaming data packets are assigned a higher priority after every hop. This can minimize the contention between the previous packet and the next packet; further, the probability of channel access for the previous packet increases. We demonstrate a better performance by modeling and simulation.
