Cooperative communication has been broadly investigated to improve performance of wireless communication. But, most of the conventional cooperative techniques have a common problem of decreased transmission rate because the destination should receive the decodable compositions of symbols from the source and the relay. In this paper, we propose the new cooperative system which uses a feedback si...

In this position paper, I argue, from previous experience working on Computer Mediated Communication and from recent experience studying contexts for computer supported cooperative work such as ambulance control and hospitals, that any use of the Clark Model in design needs to be incorporated within a more general analysis of experiencing relational activity.

Cooperative attitude regulation and tracking problems are discussed in the presence of multiple time-varying communication delays and dynamically changing topologies. In the case of cooperative attitude regulation, we propose conditions to guarantee the stability of the closed-loop system when there exist multiple time-varying communication delays. In the case of cooperative attitude tracking, ...

Both the Cooperative Computing research group at NTT and the Theory of Distributed Systems research group at MIT are carrying out research on theoretical foundations of distributed computing, with a focus on cooperative group activities in networks. Such group activities range from human social activities in cyber communities to powerful distributed applications involving data sharing and coope...

In internet of things (IoT) system, the communication scheme with reliability and low power is required to connect a terminal. Cooperative communication can achieve reliability and lower power than multiple-input multiple-output (MIMO) system. Cooperative communication increases the reliability with low power, but decreases a throughput. It has a weak point that the communication throughput is ...

IEEE 802.11a/b/g standards support multiple data rates. Although the use of multiple data rates increases the capacity of wireless networks, it can lead to a performance anomaly problem. Cooperative communication for wireless networks has attracted considerable interest owing to its ability to mitigate this performance anomaly problem. In cooperative communication, a number of relay nodes suppo...

In this paper, we propose a cooperative protocol of relay-based WUSB/DRD and WLP device in the WSS of WiMedia environment. For this, we investigate a RNT table configuration and algorithm of RNS relay node to be used in relay-based cooperative communication. Then, we describe the feature of the device to configure the WLP network and propose a cooperative protocol for WUSB/DRD/WLP device commun...
