Beamforming and Interference Mitigation in a Wireless Network Based on Swarm Behaviour
In this paper, the authors consider a ‘Swarm’ of mobile nodes that forms a wireless network. The basic idea is that two wireless nodes in the swarm (called the designated nodes) carry out all the computation. These designated nodes then share the results of the computation with all the other members of the swarm, who then use the result along with a location-based correction factor. For example, the designated nodes carry out the computation for the Direction of Arrival of signal (DoA) from a desired source. This methodology of ‘Swarm behavior’ can be applied for DoA estimation, Beamforming and tracking of the mobile source.
