On exploiting diversity and spatial reuse in relay-enabled wireless networks
Karthikeyan Sundaresan, Sampath Rangarajan · 2008
Relay-enabled wireless networks (eg. WIMAX 802.16j) represent an emerging trend for the incorporation of multi-hop networking solutions for last-mile broadband access in next generation wireless networks. The adoption of more sophisticated access technologies such as OFDM (orthogonal frequency division multiplexing) coupled with the relay-induced two-hop nature, provides two key benefits to these networks in the form of diversity and spatial reuse gains. However, leveraging these benefits calls for more sophisticated solutions, among which, user scheduling forms a key component.
