Low complexity algorithms for relay selection and power control in interference-limited environments
Abstract—We consider an interference-limited wireless network, where multiple source-destination pairs compete for the same pool of relay nodes. In an attempt to maximize the sum...

Optimal Routing for Decode-and-Forward based Cooperation in Wireless Networks
Abstract- We investigate cooperative wireless relay networks in which the nodes can help each other in data transmission. We study different coding strategies in the single-source ...

Cooperative OFDM Channel Estimation with Frequency Offsets
Abstract— This paper discusses channel estimation in a cooperative orthogonal frequency-division multiplexing (OFDM) network in the presence of frequency offsets. Both the amplif...

Equilibria and price of anarchy in parallel relay networks with node pricing
Abstract—We study pricing games in single-layer relay networks where the source routes traffic selfishly according to the strategic bids made by relays. Each relay’s bid incl...

The Impact of CSI and Power Allocation on Relay Channel Capacity and Cooperation Strategies
Capacity gain from transmitter and receiver cooperation are compared in a relay network where the cooperating nodes are close together. Under quasi-static channels, when all nodes...
