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.

MAMI: Mobile Agent based System for Mobile Internet

Accessing the Internet on the move via wireless link requires some provisioning in the network and the terminal part so that we can overcome the difficulties of wireless link, mobility, and device capability limitations. In this paper we propose a mobile agent based system for wireless mobile Internet. We use static agents (terminal and provider) at the two ends of wireless link. We represent the user by a mobile agent on the provider side, mobilize this agent when necessary. We show when, how and what to mobilize. We show that our agent based system has some desirable properties which are effective in compensating the drawbacks of wireless environment, mobile device limitations and TCP, HTTP protocol limitations in wireless environment. We describe the system architecture and operation scenario. Benefits of using agent in this scenario are discussed and we show how different optimization techniques can easily be incorporated in such a system due to its flexibility.
