QoS-aware Fast Handover Optimization Supported by Multicast Networks
Description
This paper presents three different solutions forhandover optimization covering three different scenarios. Thefirst scenario suits the needs of an operator driven networkwith no degree of liberty on the choice of the new ArcessRouter (AR) by the terminal. An higher degree of Iiberty isachieved in the second proposed solution, where a supportingmulticast network grants the non predictability of the targetAR. The multicast network altows the reduction of thebandwidth usage inside the operator network assuringresource optimization, and the delivery of the packets to thesurrounding ARs, and thus to the roaming terminal.Nevertheless, these two methods (which are operator driven)depend on an entity in the network for handover permissionand control. To avoíd this in a high mobility network, wepropose a third solution where there is no admission controland always assures available resources in the surroundingARs.
