Regulating User Arrivals at a Mobile IP Home Agent

With the increasing levels of data usage in mobile cellular networks, Mobile IP and its variants serve as the de facto standard for mobility management. At high user loads, the Mobile IP Home Agent is unable to support registration requests within the required delay limit, leading to registration failures during peak user periods. The typical way of addressing this problem currently is to over-provision the Home Agent or to add multiple Home Agents with Load-Balancing in order to handle peak loads. In this paper, the authors propose an algorithm that regulates user arrivals by manipulating their registration lifetimes, thereby smoothing the arrival process at the Home Agent.
