Abstract

Abstract

The particularity of security threats for Multi-floor building Indoor Wireless Networks (MIWNs) is mainly caused by its stochastic, dynamic and complex spatial topology. According to the features of MIWNs, such as the randomization of node distribution, complexity of spatial structure, and diversification of loss types, physical layer security technologies and stochastic geometry theory are utilized to study the cooperative secrecy transmission in MIWNs. First, a fundamental system model for MIWNs is proposed based on multi-floor Poisson point process. On this basis, cooperative transmission is introduced into MIWNs and an analysis framework to evaluate the secrecy probability for cooperative transmissions in MIWNs is proposed. Then, based on the theoretical analyses and simulation results, the influences of total floor number, secrecy rate threshold, floor number for target user, and the transmit power allocation on secrecy performance in MIWNs are examined. Finally, the simulations verify that the cooperative transmission can effectively improve the secrecy performance of the MIWNs.
