Abstract

Quality of service (QoS) provisioning in a mobile ad hoc network (MANET) is expected to become important because of the diversity of applications that these networks will have to carry. However it tends to be difficult due to constraints of MANETs such as the changing network topology, shared and variable wireless bandwidth and limited power supply. In this paper, a cross-layer scheduling approach TUBA (time urgency based algorithm) is proposed for QoS provisioning in MANETs. It takes into account the time urgency of packets and schedules the packets effectively based on the global information obtained from the network layer. In addition, TUBA can be used to improve the performance of traditional scheduling algorithms (e.g. weighted fair queueing and deficit round robin). Simulation results demonstrate the efficiency of TUBA for QoS provisioning in a MANET environment
