In this paper, the authors investigate on the problem of combining routing scheme and physical layer security in multihop wireless networks with cooperative diversity. They propose an ad-hoc natured hop-by-hop best secure relay selection in a multihop network with several relays and an eavesdropper at each hop which provides a safe routing scheme to transmit confidential message from transmitter to legitimate receiver. The selection is based on the instantaneous channel conditions of relay and eavesdropper at each hop.
