摘要：
Wireless ad-hoc networks play a significant role in environments without fixed infrastructure, especially in military and emergency situations. Due to the openness and wide coverage of wireless channel, it is necessary to establish a secure transmission mechanism against potential eavesdroppers. Traditional secure transmission schemes almost rely on single path transmission and physical layer security techniques which may not provide enough secrecy when eavesdroppers are widely distributed. To address this, in this paper, we propose a multipath secure transmission mechanism for the sake of both guaranteeing the transmission security and maximizing the end-to-end throughput. Furthermore, we give the approximated closed-form expressions of multipath secrecy connection probability (SCP) relying on secret sharing, and a novel bilevel optimization problem is formulated with the constraints of the end-to-end delay and the derived SCP. Finally, simulation results show that our proposed mechanism is beneficial concerning secrecy performance in comparison to traditional mechanisms. Also, a near-optimal throughput is obtained.
