Evaluation of an envelope-based access control scheme in multihop IEEE 802.11 ad hoc networks

Ensuring Quality of Service (QoS) guarantees for real-time traffic in ad hoc networks is challenging due to the lack of infrastructure, energy constraints, contention between packets of a flow and variability of the channel. Cetinkaya et al. designed a measurement-based admission control system that characterizes arrivals and network service by envelope processes, avoiding assumptions of constant service paths. This paper evaluates the effectiveness of Cetinkaya´s egress admission control system in ad hoc networks, particularly in a chain of nodes. Results demonstrate that the admission control system is able to keep the average packet delay below the bound.
