DACME: Distributed Admission Control for MANET Environments

DACME is a distributed admission control sytem for MANET environments that relies on end-to-end path measurements based on packet probes.

In the design of DACME we combined the IEEE 802.11e technology with probe-based admission control to achieve a novel framework for QoS support in MANETs. The implementation and deployment of DACME in real-life MANETs is effective, simple, and without constraints or strong requirements on intermediate stations participating on traffic forwarding tasks. The aim is also of supporting multipath routing protocols automatically; this means that DACME agents should operate without being aware of the routing protocol being used. At the same time, they must follow a strategy that can be deployed over both single path and multipath routing protocols without performance penalties or any other sort of problems.
