Enterprise level networks are designed to provide a fast way of communication across the globe. One of the most popular protocols used for such a network is known as Multi-Protocol Label Switching (MPLS). The fast packet forwarding mechanism from source to destination with Quality of Service (QoS) feature, MPLS is capturing a significant attention in the related market of network protocol. End nodes are expected to accomplish mobility behavior more frequently nowadays. The aim of this study is to explore, examine and propose a smooth mobility handling technique that helps in the deployment of MPLS based wireless network. There are already some proposed solutions for this problem of mobility handling, but they have certain drawbacks which are highlighted in background section. In this research work, a complete MPLS packet life cycle is described, from entering inside the MPLS clouds to reaching its destination without compromising QoS and layer overlapping. Presence of a stack at every Edge Router (ER) helps to manage packet information of missing or moved MN for future use. Simulation of the proposed idea is performed in Network Simulator (NS-2), and User Datagram Protocol (UDP) is used as the source for packet transmission from the MPLS cloud to the MN that noticeably illustrates that how the new proposed scheme is better than already proposed models. By concentrating on the packet life cycle in entire communication best results are obtained from the simulation and compared with previously proposed models. The proposed scheme has performed better with respect to packet loss, Packet Delivery Ratio [Fraction] (PDF), Normalize Routing Load (NRL) and Delay as compared to the existing solution.
