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).
