This paper outlines the implementation of collaborative beamforming to a remote low power wireless sensor network and presents its energy saving potential. The directivity procured from the beamforming allows power to be saved, which is distributed over the network. This allows each sensor within the network to have the same prolonged lifetime, and thus create a long lasting reliable network. The associated overhead with collaborative beamforming is in conjunction examined, where Single Frequency Networks (SFN) are taken as reference for synchronisation procedures. Finally, the influences of various network operating parameters on the energy benefit that can be obtained from collaborative beamforming in respect to network sizes are presented.
