Transmission of confidential messages over wireless networks between a transmitter and a receiver in the presence of illegitimate receivers called eavesdroppers is an active area of research. Cooperation by jamming can improve information-theoretic secrecy in wireless networks. However, randomly chosen jammers can have a negative impact on the secrecy capacity. Our goal is to provide a closed form for positioning the friendly jammers in two-dimensional wireless network with uniformly distributed eavesdroppers while two legitimate partners are communicating.
