Multi-Hop-aware cooperative relaying
- in Proceedings of the IEEE Vehicular Technology Conference (VTC ’09
, 2009
"... Abstract-We address the drawbacks of Cooperative Relaying regarding its spectral inefficiency and its channel over reservation compared to direct transmissions. We propose to exploit routing information in cooperative relaying to reduce these disadvantages. In this paper we present a complete syste ..."

Best-Effort Cooperative Relaying
"... Abstract—Traditional cooperative communications consider dedicated-relays, while often such relays may not be available. In this paper, we consider wireless transceivers that relay signals in addition to their own primary communication mission. We consider a best-effort delivery policy, where a node ..."

Secrecy in Cooperative Relay Broadcast Channels
, 2008
"... We investigate the effects of user cooperation on the secrecy of broadcast channels by considering a cooperative relay broadcast channel. We show that user cooperation can increase the achievable secrecy region. We propose an achievable scheme that combines Marton’s coding scheme for broadcast chann ..."

Resource Allocation for Cooperative Relaying
, 2008
"... The delay-limited capacity of the half-duplex relay channel is analyzed for several cooperative protocols under a long-term average total transmit power constraint. It is assumed that the source and the relay have access to partial channel state information in the form of channel amplitudes. Nonort ..."

Switching Rate in Selective Cooperative Relaying
"... Abstract—In selective cooperative relaying only a single relay out of the set of available relays is activated at a time, hence the available power and bandwidth resources are efficiently utilized. However, implementing selective cooperative relaying in time-varying channels may cause frequent relay ..."

Cooperative Relaying in Sensor Networks
"... Abstract—Reliable transmission of a discrete memoryless source over a multiple-relay network is considered. Motivated by sensor network applications, it is assumed that the relays and the destination all have access to side information correlated with the underlying source signal. Joint source-chann ..."

- Add to MetaCart
-channel cooperative transmission is studied in which the relays help the transmission of the source signal to the destination by using both their overheard signals, as in the classical channel cooperation scenario, and the available correlated side information. Decode-and-forward (DF) based cooperative transmission
Cooperative Relaying with Side Information
"... Abstract—We study the problem of cooperative communication in the case that the assisting node (i.e. the relay) has access to correlated information about the source that needs to be reconstructed at the destination. Finding the relaying strategy that minimizes the reconstruction distortion at the d ..."
