Abstract / Description of output

We propose MWAN, a multi-rate network model to deliver differentiated service in a wireless mobile ad-hoc network (MANET) with varying physical-layer link speed. The proposed architecture is modelled using a multi-dimensional Markov chain to support both real-time and non-real-time applications. It is demonstrated that various types of data arrival process can be modelled by a Markov Modulated Arrival Process (MMAP). Numerical analyzes are drawn to estimate the packet drop probability, effective throughput and packet queuing delay. We validate the scheme by simulating under different link utilizations with IEEE 802.11 Distributed Coordination Function (DCF) ad hoc mode. Analytical and simulation results are compared to determine the accuracy of the presented methods. Increased Quality-of-Service (QoS) performance is achieved for high priority traffic.
