A predictive end-to-end QoS scheme in a mobile environment

Abstract

Mobility is one of the new services that have been introduced due to the development and popularity of the Internet. However, the Internet currently lacks quality of service support. This article presents an end-to-end QoS architecture for roaming terminals. This architecture is based on mobile IP reservation protocol (MIR), hierarchical mobile IP (HMIP) and Diffserv. MIR operates within the wireless environment inside a HMIP domain while Diffserv mechanisms provide end-to-end QoS. MIR addresses the problem of bandwidth and reservation in order to provide users of a shared medium with a guaranteed bandwidth. Resources are reserved in the cells where mobile nodes are likely to go.
