Simultaneous Mobility in MPLS

Abstract

The movement of a mobile device is likely during its communication with other mobile or stationary nodes. This movement results in what is known as the mobility problem. The general mobility problem has been addressed by the Mobile Internet Protocol (MIP). However this solution only takes care of the scenario where there is only one mobile node communicating with a stationary node. Simultaneous Mobility Problem arises when both the communicating nodes in a network are mobile, a scenario not dealt with by the basic mobility protocols. When both communicating nodes move and update each other with their latest locations, the updates can be lost as a result of their simultaneous movement. Thus the communicating nodes are not able to find the current location of each other. Solutions for Simultaneous Mobility solutions have been discussed previously. In this paper we propose a solution to the problem of Simultaneous Mobility in a Multi Protocol Label Switching domain.
