Cooperative MIMO communication is a promising technology which enables realistic solution for improving communication performance with MIMO technique in wireless networks that are composed of size and cost constrained devices. However, the security problems inherent to cooperative communication also arise. Cryptography can ensure the confidentiality in thecommunication and routing between authorized...
Wireless Sensor networks (WSNs) require energy-efficient and robust communication protocols. Cooperative MIMO transmission is one of the new solutions. In this paper, we propose an Energy-efficient Cluster-based Cooperative MIMO transmission scheme using Network Coding, termed as ECCM-NC. Network coding algorithm is applied to reduce the energyand time consumption in intra-cluster information exchange...
Emerging cooperative MIMO communication is a promising technology in improving communication quality for wireless sensor networks. However, the security problems inherent to cooperative communications also arise. In this paper we investigate the situation where some of the cooperative nodes are compromised and try to corrupt the communications by sending garbled signals. To combat the compromised...
In this paper, the authors propose a cross-layer security scheme for virtual MIMO networks. The scheme combines cryptographic technique implemented in higher layers with data assurance analysis at the physical layer to provide better security. The scheme can, of course, be used for a traditional non-cooperative MIMO network. First, the authors show an efficient key management system that can provide...
In virtual MIMO technology, distributed single-antenna radio systems cooperate on information transmission and reception as a multiple- antenna MIMO radio system. In this paper, a new virtual MIMO communication scheme and routing protocol are cross layered designed for a wireless sensor network (WSN) to jointly achieve reliability, energy efficiency and delay reduction. The proposed communication...
