Sammendrag
Wireless sensor network (WSN) plays a fundamentally important role in the realization of Internet of Things and Industry 4.0. In this letter, we study the physical layer security performance of a large-scale ad hoc and homogeneous WSN. To accurately evaluate the secrecy performance of the large-scale WSN, we take into account the randomness of the interfering nodes (both in terms of the number of nodes and their respective position) based on Poisson point process (PPP) in our analysis. We derive novel expressions for the average secrecy capacity (ASC) and secrecy outage probability (SOP) including the effects of fading, path loss, and the network's spatial randomness. The results demonstrate the impacts of several factors such as node intensity, transmission power in large-scale WSN on secrecy performance, which should be seriously taken into consideration while designing WSNs.
