摘要：
Achieving QoS (Quality of Service) in Mobile Ad-hoc NETworks (MANET) has been a research topic in the last years. In this paper we describe an adaptive QoS reservation mechanism for Multirate Adhoc Networks. The mechanism is targeted for sources requiring a bandwidth allocation. The scheme consist of the nodes initially computing the available bandwidth for new reservations, using the state information advertises among the neighbors. Then, the nodes adjust the available bandwidth by measuring the effective transmission rate achieved while transmitting packets. Simulation results show that the available bandwidth computed by the proposed scheme adapts fast and accurately to changing network conditions.
