Queued Cooperative Wireless Networks Configuration Using Rateless

Queued Cooperative Wireless Networks Configuration Using Rateless Codes

Abstract: A system using cooperative communication with rateless codes is presented that uses communication transmission aspects of cooperative communication with rateless codes over Rayleigh fading channels and queuing aspects for buffering messages at intermediate relays. The system transmits a subsequent message while a current message is en route to the destination by receiving and buffering the current message in queues at intermediate relays. A relay with a best instantaneous communication link to the source may receive a message first and forward the received message to the destination. Alternatively, if inter-relay communication links are strong, all relays may cooperate simultaneously.

Specification

Cooperative communications, where different nodes in a network work together to transmit information from a source to a destination, decreases energy expenditure and improves reliability of data transmission in a wireless network. A variety of cooperation schemes have been proposed, such as cooperative beam-forming, distributed space-time codes, amplify and forward signaling, decode and forward signaling, dynamic decode and forward signaling, etc.
