Abstract :
In energy efficient, present cooperative beam forming for wireless ad-hoc networks via cooperative beamforming, nodes in wireless network are able to transmit a common message over a long distance in an energy efficient manner. To improve the performance, have developed a cooperative beamforming algorithm. The idea of cooperative beamforming is to take the help of neighboring nodes to form a beam of electromagnetic energy i.e., the idea of antenna array is used. Since in this type of network the nodes cannot have antenna array to implement beamforming, so take the help of nearby node to participate in beamforming process. Source node in the network is allowed to transmit and collaborating nodes receive the transmitted packets. Subsequently each collaborating node transmits its received signal. One or multiple beams are formed each focusing on one destination node and reinforcing the signal intended for a particular destination as compared to the other signals. The proposed work achieves higher throughput and improved Signal to Noise Ratio in the ad-hoc network.
