Abstract :
With the fast development of information technology, the application environment and multimedia services in ad hoc networks, all of these are needed to support QoS. High-efficient and reasonable MAC protocol is the key point to provide QoS support in the network. In this paper, we analyze some typical QoS MAC protocols, and propose an adaptive QoS MAC protocol-AQMP, which is based on IEEE802.11 protocol. In this protocol, different priority classes can be assigned for different traffics, and nodes in the network can participate in channel contention adaptively, and nodes perform backoff mechanism adaptively. Analysis and simulation result show that compared with model MAC protocol, AQMP protocol provides better QoS support for higher priority traffics, solves hidden terminal problems, and also considers the fairness issues between different network nodes.
