Applications based on the Internet of Things (IoT) require robust and energy efficient communication protocols to maximize the network lifetime. Radio irregularity, channel fading and interference results in larger energy consumption and latency for packet transmission over wireless channel. This paper investigates the use of cooperative Multi-Input Multi-Output (MIMO) scheme to protect the transmission of confidential and private messages in the IoT with high energy savings. To this purpose, an expression of the MIMO Gaussian wiretap channel problem in the IoT context is developed. An algebraic expression is established for the capacity-equivocation region of the virtual cooperative communication channel. Simulation results show that the proposed virtual MIMO scheme performs betters when the order of diversity increases.
