Code Design for Multihop Wireless Relay Networks

We consider a wireless relay network, where a transmitter node communicates with a receiver node with the help of relay nodes. Most coding strategies considered so far assume that the relay nodes are used for one hop. We address the problem of code design when relay nodes may be used for more than one hop. We consider as a protocol a more elaborated version of amplify-andforward, called distrib...

Routing metrics design for multihop wireless networks

The design of a routing protocol must be based on the characteristics of its target networks. The diversity of wireless networks motivate the design of different routing metrics, capturing different aspects of wireless communications. The design of routing metrics, however, is not arbitrary since it has a great impact on the proper operation of routing protocols. Combining a wrong type of routi...

Multihop Relay-Enhanced WiMAX Networks

The demand for high speed data service has been increasing dramatically since the Internet has become a part of people’s lives. Most broadband wireless service providers have boosted data service rates by adopting recently developed technologies such as OFDM, MIMO, and smart antennas. However, in practice there are still problems such as coverage holes due to shadowing, and poor signal to inter...
