SRL-Enabled QoS model for mobile ad hoc networks

摘要

Due to the dynamic network topology and bandwidth constraints of Mobile Ad hoc NETworks (MANETs), existing quality of service (QoS) models for wired networks, i.e. Integrated Service (InteServ) and Differentiated Service (DiffServ) are not applicable on MANETs. In this paper, we propose the SRL-Enabled QoS Model (SEQM) for MANETs by extending a QoS routing protocol: Supernode-based Reverse Labeling (SRL) algorithm, which considers QoS provisioning, specifically bandwidth and delay together. SRL utilizes a hierarchical structure to improve performance and enhance QoS routing. Besides extending SRL with on-demand service proxy, SEQM also includes dynamic traffic negotiation and resource provisioning. Preliminary simulation results show that SEQM performs effectively in terms of throughput and end-to-end delay.
