In this paper, the stability analysis and control design of heterogeneous traffic flow is considered. It is assumed that the traffic flow consists of infinite number of cooperative non-identical vehicular platoons. Two different networks are investigated in stability analysis of heterogeneous traffic flow: 1) inter-platoon network which deals with the communication topology of lead vehicles and...

Cognitive Radio provides enhanced wireless communication performance through context-aware sensing and adaptation. Cooperative relay enhances network connection quality and improved system throughput. Applying cooperative relay communication technique on Cognitive Radio networks enables Cognitive Radio to opportunistically exploit cooperation between network nodes. This integrated design that b...

We consider a cognitive radio network scenario where a primary transmitter and a secondary transmitter, respectively, communicate a message to their respective primary receiver and secondary receiver over a packet-based wireless link, using a joint automatic-repeat-request (ARQ) error control scheme. The secondary transmitter assists in the retransmission of the primary message, which improves ...

The broadcast nature of wireless communications suggests that a source signal transmitted towards the destination can be “overheard” at neighboring nodes. Cooperative communication refers to processing of this overheard information at the surrounding nodes and retransmission towards the destination to create spatial diversity, thereby to obtain higher throughput and reliability. In this paper w...

Research in Information Systems has switched its focus from data to communication. The communication between different autonomous Information Systems requires a certain amount of intelligence of each system. The system should be able to know which queries it can/may handle and also be able to negotiate about the information that it will give. In short, these systems evolve into what is called C...

Cooperative communication is an attractive solution to combat fading in wireless communication systems. Achieving synchronization is a fundamental requirement in such systems. In cooperative networks, multiple single antenna relay terminals receive and cooperatively transmit the source information to the destination. The multiple distributed nodes, each with its own local oscillator, give rise ...

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 the communication and routing between auth...

As pointed out by the literature, the recent growing interest in cooperative work studies is motivated by technological and organizational changes and by the design of computer systems for cooperative activity which requires models of human-human cooperation. The analysis of communications between group members is one of the powerful tools to identify and describe the functioning of cooperative...

In this chapter, we focus on the energy efficient cooperative communication with random node cooperation for wireless networks. By “random,” we mean that the cooperative nodes for each communication event are randomly selected based on the network and channel conditions. Different from the conventional deterministic cooperative communication where cooperative nodes are determined prior to the c...
