Relay Selection for Low-Complexity Coded Cooperation
— This paper explores relay selection and selection diversity for coded cooperation in wireless sensor networks, with complexity constraints for the sensor nodes. In previous wor...

Forward Correction and Fountain codes in Delay Tolerant Networks
Abstract—Delay tolerant Ad-hoc Networks leverage the mobility of relay nodes to compensate for lack of permanent connectivity and thus enable communication between nodes that are...

On the distortion exponents of layered broadcast transmission in multi-relay cooperative networks
In this paper, we consider the transmission of a Gaussian source over a cooperative relay network, and analyze its end-to-end distortion at high signal-to-noise ratio, in terms of ...

Cooperative Uplink of Two Mobile Stations with Network Coding Based on the WiMax LDPC Code
We consider the uplink of two mobile stations with the help of one common relay. Recently, joint network-channel coding based on LDPC codes was proposed for this setup where the ch...

Relay vs. User Cooperation in Time-Duplexed Multiaccess Networks
The performance of user-cooperation in a multi-access network is compared to that of using a wireless relay. Using the total transmit and processing power consumed at all nodes as...
