Design and Simulation of A QoS Signaling Protocol for Mobile IP Networks

The coupling of signaling protocols for mobility management and resource reservation plays an important role to achieve quality-of-service (QoS) in mobile environments. When performing a handover, request and allocation of resources have to be done in the shortest possible time to avoid disruptions for the user service. In this paper, we analyze the effects of node mobility on the interaction between QoS signaling protocols and mobility management protocols, and how the protocols operate in different mobility scenarios. We also propose an efficient QoS signaling protocol which operates adaptively in mobile IP networks. The key features of the protocol include crossover node discovery and local repair to achieve seamless services. Our simulation and experimental results show that the proposed protocol works well in mobile environments.
