Mobility Beamforming Prediction and a Round Robin Scheduling in a Directional MAC for MANET

In pervasive directional beamforming mobile network environments, the mobility of nodes could bring to an excessive loss of synchronization between couples of nodes which are performing a communication; this issue is also known as handoff problem. This kind of problem usually contribute to dramatically reduce the network performance especially at MAC (Medium Access Control) layer. Although sectorized approaches could be used in order to limit this issue, an high accuracy in the estimation of the future position of the nodes is required for granting the mitigation of the handoff and at the same time an overall improvement of the network performance. In view of this, we propose a versatile predictive location mechanism that provides for an high-efficiency tracking of the position of the nodes by using a frame scheduler with priority.
