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.
