Abstract :
To conduct collaborative beamforming in wireless ad hoc or sensor networks, several protocols must be executed, including the localization protocol, time synchronization protocol, and data dissemination protocol. In practice, however, these protocols are often limited by their complexities for achieving the ideal perfect performance. Therefore, protocol defects such as location errors, time synchronization errors, and message losses often appear in collaborative beamforming with distributed operations. In this paper, we introduce an analytical framework to analyze the impact of protocol defects on the performance of collaborative beamforming. We show numerical results of the proposed model, and explain how the proposed model can be used to mitigate the impact of protocol defects for collaborative beamforming in wireless networks.
