Abstract

The main purpose of this paper is to propose mobile IP network architecture based on dense wavelength-division multiplexing (DWDM), with GMPLS as a common control plane of the optical layer. A novel probability-based wavelength assignment (PWA) scheme for facilitating handoff in the proposed GMPLS-based mobile IP network is also presented. This paper studies the effects of network mobility and handoff path rerouting on the wavelength assignment scheme in a GMPLS-based mobile IP network. In order to support the same quality of service (QoS) for mobile services when handoff occurs, it is preferable to use the same wavelength in the newly established partial label switched path (LSP). In the proposed PWA scheme, when a mobile router (MR) begins to establish a new connection with the correspondent node, a wavelength is assigned based on the vacant probability of every wavelength in the new partial LSP after handoff. We use M/M/1(0) queue to model the dynamic traffic in a GMPLS-based mobile IP network and derive the close-form expression of wavelength vacant probability.
