Abstract
In order to obtain better performance in wireless ad hoc networks, the majority of existing work focuses on the multi-priority based packet scheduling mechanism under multiple service classes, admission control and rate policing, according to application requirements and network conditions. In addition, no studies have reported on the feasibility and scalability of adapting the IEEE 802.11 EDCA scheme in such networks. This paper presents a new QoS provisioning model called Dynamic Hop Service Differentiation (DHSD), which performs dynamic class selection based on estimation of each service class (AC) in 802.11e based ad hoc networks. This model is designed for Soft QoS provisioning. Performance evaluation is performed by simulation using OPNET. It is demonstrated that this QoS model outperforms existing service models in wireless ad hoc environments.
