As network environments with multi-radio access technologies become the norm, dynamically choosing the most appropriate network interface and base station becomes essential for distributing radio resources optimally and fairly, and for allowing each mobile node to take full advantage of its multiaccess capability based on its particular needs and criteria. In these increasingly complex scenarios the importance of handover decisions cannot be underestimated.
This series of projects aim at using simulation to study different handover decision strategies, focusing on the tradeoffs between continuous connectivity, network utilization and performance, and the associated costs. In order to achieve this, we must also develop appropriate and effective simulation tools on top of pre-exisiting open-source network simulator environments.
