Defending Against Eavesdropping Attack in WSNS: A Co-Operative Beam Forming & Jamming Approach

Security at physical layer in Wireless Sensor Networks (WSNs), where each node has single antenna. To form a architecture of MIMO communication system, the sensor node support at each cluster of the network. Here we propose Cooperative Beam forming & Jamming (CBJ) approach to enhance the security of WSNs. In network some part of sensor nodes at transmitter (Alice) side are used to transmit beam forming signal to receiver (Bob). In same network, some of sensor nodes at bob side are used to create artificial noise (AN) to jam the Eavesdropper (Eve). Keywords - Artificial Noise; Beam forming; Jamming
