Physical layer security-aware routing and performance tradeoffs in ad hoc networks

Abstract

Abstract-The application of physical layer security in ad hoc networks has attracted considerable academic attention recently. However, the available studies mainly focus on the single-hop and two-hop network scenarios, and the price in terms of degradation of communication quality of service (QoS) caused by improving security is largely uninvestigated. As a step to address these issues, this paper explores the physical layer securityaware routing and performance tradeoffs in a multi-hop ad hoc network. Specifically, for any given end-to-end path we first derive its connection outage probability (COP) and secrecy outage probability (SOP) in closed-form, which serve as the performance metrics of communication QoS and transmission security, respectively. Based on the closed-form expressions, we then study the security-QoS tradeoffs to minimize COP (resp. SOP) conditioned on that SOP (resp. COP) is guaranteed. With the help of analysis of a given path, we further propose the routing algorithms which can achieve the optimal performance tradeoffs for any pair of source and destination nodes in a distributed manner. Finally, simulation and numerical results are presented to validate the efficiency of our theoretical analysis, as well as to illustrate the security-QoS tradeoffs and the routing performance.

“…On the other hand, to limit the information leakage at bit-level, the physical layer security technique is exploited to guarantee the secure video transmission [114]. Moreover, physical layer security aware routing for multi-hop ad hoc networks are investigated [115][116][117]. Other researchers study the physical layer authentication [118,119].…”

“…Later, Yao et al [23] studied the PLS-based routing in a multihop wireless network with the decode-and-forward relaying scheme. In our previous studies [43]- [45], we investigated that how to design the routing protocol which can guarantee the transmission security while ensuring the communication quality of service, and explored the tradeoff issue between the two aspects. More recently, Xu et al [46] designed a secure routing mechanism for multi-hop cognitive radio networks with the aid of artificial noise.…”

“…Meanwhile, diverse applications of PLS in wireless communication systems have been proposed in the literature. For example, the works of [14]- [16] studied PLS for 5G wireless networks; the works of [17]- [23] discussed the cooperative jamming and relay selection strategies in two hop cooperative networks with the consideration of PHY-SCE; the works of [24]- [27] explored the PLS based routing in multi-hop wireless networks.
