This paper proposes a tractable analysis framework to evaluate the reliability, security and secrecy energy efficiency (SEE) performance in a communication network with mobile sinks via a threshold-based access scheme and multi-antenna technique. Specifically, the mobile sinks, legitimate receivers and eavesdroppers are deployed randomly. To achieve reliable results for general communication scenarios, this paper assumes both line-of-sight and non-line-of-sight paths with Rayleigh fading for air-to-ground channel model. In particular, we first exploit the association probability of a randomly located receiver and the activation probability of mobile sinks. Then, we analyze the security, reliability, and SEE of the networks with mobile sinks. Simulation results are finally provided to show the effect of the predetermined access threshold, the transmitter's resource block, the height of mobile sinks, the density of legitimate receivers, and the density of eavesdroppers on the reliability as well as security performance, and determine the optimal design parameters for a given network with mobile sinks to maximize the SEE.
