— Cooperative diversity obtains the spatial diversity gains created by sharing antennas of terminals in wireless networks. In this paper, adaptive amplify-and-forward (AF) cooper...
— This paper considers a fading relay channel where the total transmit power used is constrained to be equal to that of the standard single-hop channel. The relay channel used op...

— We study the cross-layer problem of combining routing and cooperative diversity in multi-hop, bandwidthconstrained networks with dedicated multiple access. Previous work in coo...
— Routing in wireless networks confronts more diverse and more rapidly varying characteristics associated with wireless links. Several recent protocols have tried to exploit coop...
— This paper proposes a medium access control (MAC) algorithm, called Cooperative Diversity MAC (CD-MAC), which exploits the cooperative communication capability to improve robus...

—We consider a cooperative diversity scheme where a relay cooperatively enhances communication between a source and destination. In cooperative diversity, due to lack of a mechan...

— In this paper we study a simple protocol utilizing two-hop cooperative diversity augmented with “automatic repeat request” (ARQ) for multi-hop ad-hoc networks. This protoco...
—Existing cooperative diversity protocols are designed with the inherent assumption that users exhibit cooperative behavior all the time. However, in a practical cooperative wire...
