AC and QAR for Provisioning of QoS in MANETs
Independent thesis Advanced level (degree of Master (Two Years))Student thesis
Mobile Ad-hoc network (MANET) is a collection of mobile nodes which communicate over wireless channels without any centralized control or existing infrastructure. The freely movement of nodes allow them to join or leave the network independently. Due to node mobility, wireless channels and limited resources makes the provision of Quality of Services (QoS) in MANETs very challenging. With the emerging use of multimedia applications over MANETs which requires different types of QoS provision from the networks. The Admission Control (AC) and QoS-Aware routing (QAR) protocols have made a progress in provision of QoS up to some extents. In this thesis, various AC and QAR protocols are reviewed and their characteristics and limitations are identified. We also make a comparison between DSR and AODV routing protocols in different network scenarios.
The literature study shows that the performance of network layer best-effort protocols has been improved with the use of QAR and AC protocols to sustain the QoS requirements of the applications. In current literature AC and QAR protocols are satisfying single metric of QoS. At the same time different applications such as multimedia applications which require various types of assurance from the network on the Quality of services (QoS) The simulation results show that DSR performance is better than AODV when we have less traffic load.
