“…Collaborative Beamforming (CB) and Cooperative Transmission (CT) have been proposed as new communication techniques guaranteeing spatial and multiuser diversity. The fundamental idea is to allow all the sensor nodes helping transmit and forward information to each other [3]. As a result, the collaborating nodes will create a virtual Multiple-Input/Multiple-Output (MIMO) communication system.…”

“…Nonetheless, the direct application of MIMO to IoT is impractical since the nodes have a small physical size that prevents the support of multi-antenna technology. To cope with this limitation, some approaches have been recently proposed in the literature to implement cooperative transmission/reception schemes in order to set up virtual MIMO systems [3,4]. This paper proposes a secure MIMO communication system for the IoT.…”

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.
