Enhancement of IP QoS during handoff in Mobile IP and DiffServ network

Real-time application is one of the dominant types of traffic transported through mobile Internet protocol (MIP). The performance of the network is very dependent on the non real-time applications. Provisioning quality of service (QoS) architecture by using differentiated service (DiffServ) has proven to be more scalable in handling real-time traffic. This paper shows how to provide an acceptable fairness for better QoS support for real-time traffic transfer in Internet. The study of the proposed scheduling algorithm named round robin priority queuing (RRPQ) in DiffServ network has been carried out through simulation work using ns2.
