Group Handover Management in Mobile Femtocellular Network Deployment

The mobile femtocell is the new paradigm for the femtocellular network deployment. It can enhance the service quality for the users inside the vehicles. The deployment of mobile femtocells generates lot of handover calls. Also, number of group handover scenarios are found in mobile femtocellular network deployment. In this paper, we focus on the resource management for the group handover in mobile femtocellular network deployment. We discuss a number of group handover scenarios. We propose a resource management scheme that contains bandwidth adaptation policy and dynamic bandwidth reservation policy. The simulation results show that the proposed bandwidth management scheme significantly reduces the handover call dropping probability without reducing the bandwidth utilization.

Handover Call Admission Control for Mobile Femtocells with Free-Space Optical and Macrocellular Backbone Networks

The deployment of mobile femtocellular networks can enhance the service quality for the users inside the vehicles. The deployment of mobile femtocells generates a lot of handover calls. Also, numbers of group handover scenarios are found in mobile femtocellular network deployment. The ability to seamlessly switch between the femtocells and the macrocell networks is a key concern for femtocell network deployment. However, until now there is no effective and complete handover scheme for the mobile femtocell network deployment. Also handover between the backhaul networks is a major concern for the mobile femtocellular network deployment. In this paper, we propose handover control between the access networks for the individual handover cases. Call flows for the handover between the backhaul networks of the macrocell-to-macrocell case are proposed in this paper. We also propose the link switching for the FSO based backhaul networks. The proposed resource allocation scheme ensures the negligible handover call dropping probability as well as higher bandwidth utilization.
