We consider two sources in a wireless network exchanging stochastically varying traffic
using an intermediate relay. Each relay use incurs some cost, which, for example, could be …

We consider a scenario in which two sources exchange stochastically varying traffic with the
aid of a bidirectional relay that may perform network coding over the incoming packets. Each …

We study routing and scheduling algorithms for relay-assisted, multichannel downlink
wireless networks [eg, orthogonal frequency-division multiplexing (OFDM)-based cellular …

We consider a relay node that stochastically receives packets from two opposing flows.
Whenever opportunities exist, the relay performs network coding to efficiently transmit …

In this paper, we consider a three-node, two-way relay system with digital network coding.
The aim is to minimize total energy consumption while ensuring queue stability at all nodes …

We consider a pair of nodes who wish to communicate with each other via intermediate
relays. In this bi-directional network with stochastic flows, we develop the throughput optimal …

In a recent paper, we demonstrated the minimization of instantaneous energy in a two-way
relay network with digital network coding at the relay, through the optimization of the time …

We consider a pair of nodes with stochastic traffic flows who wish to communicate in a bi-
directional communication scenario using intermediate relays in two-hop fashion …

Extensive research in recent years has shown the benefits of cooperative relaying in
wireless networks, where nodes overhear and cooperatively forward packets transmitted …

In this paper, we consider a wireless amplify-and-forward relay network with one relay node
and multiple source-destination pairs/users and propose a pricing framework that enables …
