What is Distributed Cooperative Relaying

Encyclopedia of Information Science and Technology, Fourth Edition
The mapping of the rationale behind spatio-temporal processing onto networked systems where designated Relay Nodes may form Virtual Antenna Arrays and, given proper synchronization, provide better transmission robustness or throughput.

When perceived from the perspective of Physical Layer upwards, as it capitalises on signal processing in both the spatial and temporal domains, the concept of Link Layer inherent Distributed Cooperative Relaying based on Virtual Antenna Arrays aims to improve the reliability of wireless communications through the exploitation of radio diversity provided by Relay Nodes. Given such a context, the inclusion of Network Layer routines of relevance may only further facilitate the orchestration of networked devices in terms of arranging for their pre-selection into cooperative groups. However, as the system becomes more and more complex, it appears of necessity to incorporate overlay elements of self-management driven Generic Autonomic Network Architecture to allow simultaneous formation of numerous cooperative and non-cooperative set-ups. This is where the substantial role of autonomic system design comes into the global picture as the umbrella under which the concept of Autonomic Cooperative Communications may be realised.
