Secure communication over large-scale decentralized wireless networks is an extremely challenging task due to the cost and difficulty in establishing secret keys among all the nodes in a distributed manner. For this reason, the notion of physical layer security has recently drawn significant attention, which may assist with key exchange and provide an additional layer of protection in such networks. In this paper, the authors investigate how the physical layer security constraints affect the network throughput. They consider a random network in which the legitimate and eavesdropper nodes are located according to independent Poisson point processes.
