Abstract

This paper proposes a scheme to provide in a CSMA/CA based multihop wireless ad hoc network, a consistent and accurate proportional differentiation in average end-to-end packet delay. The proposed scheme, called PDMED uses a cross-layer approach that requires a distributed scheduler to adapt to the information from a QoS monitor, a route monitor and a channel monitor. Conceptually, the distributed scheduler dynamically adjusts the backoff duration of a flow based on its instantaneous deviation from the maximum average end-to-end packet delay. This is done such that a flow with a larger deviation from the maximum is given a longer backoff duration to give way to transmissions from other flows with smaller deviations. PDMED has been extensively evaluated through random event simulations using OPNET. The results confirm that it is capable of providing a consistent and accurate proportional differentiation, which is other-wise not achievable under various traffic conditions.
