چکیده مقاله:
In this paper a new strategy of fountain code transmission over cooperative relay networks is proposed. The rateless characteristic of fountain codes makes them suitablefor sending data over erasure channels. In addition, the presence of relay nodes can help to improve the performance.Until now, traditional rateless codes, rarely use feedbackcommunication channels between receivers and broadcasters, a feature that is available in many wireless settings and helps tohave better performance. Thus, in this paper we provide a feedback channel between the destination and the relay in orderto help the relay to have more efficient transmissions. It ends to decrease the overall overhead in transmission over erasure channels. Thereby, significant savings in time and energy are obtained.
