Mobile IP (MIP) is the current standard for supporting mobility in wireless mobile networks. However, the latency and packet losses faced during handovers may significantly degrade the quality of seamless connection in Mobile IP. Thus, minimizing handover latency and the number of lost packets during a handover is an important task in wireless mobile networks. In this paper, we propose a new mobility management scheme to handle the movements of Mobile Nodes (MNs) among different cell in the same wireless network to reduce data loss and maintain uniform connectivity. We also provide the performance results both for the proposed and basic horizontal handovers in wireless mobile networks. The simulation results show that the proposed model profoundly decreases latency at the expense of slightly increased data traffic.
1. Introduction
Wireless networking has become an increasingly important way to provide global information access for users regardless of time and location. Mobile IP (MIP) is the current standard for supporting mobility in wireless networks [1]. MIP provides a good framework for allowing users to roam outside their home networks. However, the MIP model needs to be enhanced to manage the movement across multiple subnetworks within a single network or domain. MIP may result in disruption to user traffic during handoff; it also has high control overhead due to frequent notifications to the home network resulting in high packet loss and high handover latency. Thus, minimizing...
