Abstract: This paper discusses the collaborative beamforming problem using improved directional perturbation approach based on one bit feedback scheme. There are multiple transmitters and one receiver in our setup, all the transmitters send a common signal synchronously, the receiver return a one bit of feedback to the transmitters. Each transmitter uses only the one bit feedback and local information to adjust its phase in every time slot. An algorithm using directional perturbation approach based on one bit feedback is proposed to improve the convergence accuracy. The convergence properties of phase alignment are investigated by simulation, and the simulation results verify that the convergence accuracy of the proposed algorithm outperforms the original algorithm. Moreover, simulations also show that the proposed algorithm has advantages on scalability.

Abstract: The life of Sensor Network (SN) is mainly dependent upon power consumption. If the power dependence is managed efficiently, the network can go on for longer. Different protocols have been developed for power reduction of the sensor networks which have greatly minimized the power consumption of the said networks. Analysis of different routing protocols in WSN, and the results show major advancement in the life span of wireless sensor networks. In this paper classification and comparison of routing protocols in reduction of power consumption in wireless sensor networks will be present.
