Enhancing QoS support in Mobile Ad Hoc Networks

Due to resource constraints and dynamic topology of Mobile Ad Hoc Networks (MANETs), supporting Quality of Service (QoS) in MANETs is a challenging task. Although lots of research have been done on supporting QoS in the Internet and other networks, they are not suitable for the MANET environment. This paper provides a brief review of the current researches on QoS support in MANETs and proposes a new model for enhancing QoS support in MANETs. Through extensive simulation, we observe and analyze the performance of the network in terms of throughput and average delay. A thorough investigation of the performance of higher and lower priority traffic is made under different traffic loads and mobility scenarios. The simulation results show an improvement of the performance of our QoS model as compared to SWAN[7].
