A new Variable Error Metric adaptive beamforming Algorithm for smart antenna systems

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

“…As instrument for our model implementation we chose the Omnet++ Simulator; we used the adaptive Smart Antenna PhasedArray module designed in [16]. For enabling the Round-Robin approach we extended PhasedArray module adding several configuration variables (such as sectorTime and sectorWidth) and a set of utility functions.…”

A Low Energy Consumption Smart Antenna Adaptive Array System for Mobile Ad Hoc Networks

“…However, when the energy saving algorithm is not used by the system, we still have a remarkable improving of the average Packet Delivery Ratio with respect to the omnidirectional case. As future developments, we will propose to optimize the system replacing the LMS algorithm (that could result very slow in terms of computations as the number of communications increases) with a faster algorithm that provides a Variable Error Metric estimation (VMA) that we designed in [29]. Other aspect that it needs to be investigated is the node density; in particular, in order to have a precise estimation of the error introduced by interfering signals in environments in which the concentration of nodes is high, it could be necessary to implement an accurate caching mechanism; in this regard, it might result very critical to distinguish the amount of destructive power introduced mainly by the closest neighbors of a certain transmitter/receiver node, especially in contexts that changes their topology very frequently.…”
