We investigate the risk associated with multihop wireless communications due to
eavesdropping. When the same message traverses cross a multihop wireless network …

This paper considers secure energy-efficient routing in the presence of multiple passive
eavesdroppers. Previous work in this area has considered secure routing assuming …

Friendly jamming is a physical layer security technique that utilizes extra available nodes to
jam any eavesdroppers. This paper considers the use of additional available nodes as …

We investigate the problem of eavesdropping control in wireless communications networks.
When a confidential message is transmitted through a wireless network, there is a potential …

This paper studies finding the secure path according to the secrecy connectivity probability
(SCP) in the multihop ad hoc networks in the presence of inhomogeneous eavesdropper …

Information-theoretic security constraints reduce the connectivity of wireless networks in the
presence of eavesdroppers, which motivates better modeling of such networks and the …

Multipath routing can offer various advantages for wireless multihop networks. Among those
advantages, in this paper, we focus on an advantage of multipath routing for security using …

In this paper, we consider the problem of joint secure routing and transmit power
optimization for a multi-hop ad-hoc network under the existence of randomly distributed …

Two-hop relay wireless network serves as an important network model for the performance
study of general wireless networks, while cooperative jamming has been a promising …

Signal interference and packet collisions are typically viewed as negative factors that hinder
wireless communication networks. When security is the primary concern, signal interference …
