Admission control and simple class based QoS provisioning for mobile ad hoc network

In this paper, we present a network layer based admission control and simple class based service differentiation model to support QoS in mobile ad hoc networks. Our admission control procedure works along with the route finding phase of reactive routing protocols for mobile ad hoc networks (AODV, DSR etc). We also propose a simple class based service differentiation system to support QoS once a traffic is admitted by our admission controller. The proposed service differentiation is based on a DiffServ model and includes modifications like configuration of each node with edge and core functionality, dynamic selection of edge/core functionality, and use of minimal and simple classes. Simulation results show that our system allows seven times more real time traffic in the network than the proposed QoS for the AODV model while satisfying the demanded end-to-end delay and providing low jitter.
