It is known that the achievable data rate per user can be increased when relays are
deployed in wireless networks. However, the drawback of this solution is that some of the …

Wireless relay nodes can improve the capacity of wireless networks. In this work, we
integrate wireless relay nodes into the infrastructure of a wireless local area network …

The performance of a relay-based cellular network is greatly affected by the relay location
within a cell. Existing results for optimal relay placement do not reflect how the radio …

We use information theoretic achievable rate formulas for the multi-relay channel to study
the problem of as-you-go deployment of relay nodes. The achievable rate formulas are for …

We use information theoretic achievable rate formulas for the multi-relay channel to study
the problem of optimal placement of relay nodes along the straight line joining a source …

Relay stations (RSs) are usually used to enhance the signal strength for the users close to
the cell boundary. However, transmission through a relay station needs two transmission …

In this paper, we address the problem of optimally placing relay nodes in a cellular network
with the aim of maximizing cell capacity. In order to accurately model interference, we use a …

Given n source nodes and k relay nodes, we model the optimal relay topology problem
allowing for simultaneous optimization of the relay node locations and traffic through the …

This paper considers the problem of selecting a subset of nodes in a two-hop wireless
network to act as relays in aiding the communication between the source-destination pair …

Digital relaying is a technique that uses certain mobile terminals that have good
communication links with the base station to act as relay nodes for those that do not have …
