SOLOR: Self-Optimizing WLANs with Legacy-Compatible Opportunistic Relays

Current IEEE 802.11 WLANs suffer from the well-known rate anomaly problem, which can drastically reduce network performance. Opportunistic relaying can address this problem, but three major considerations, typically considered separately by prior work, need to be taken into account for an efficient deployment in real-world systems: relaying could imply increased power consumption, and nodes might be heterogeneous, both in power source (e.g., battery-powered vs. socket powered) and power consumption profile; similarly, nodes in the network are expected to have heterogeneous throughput needs and preferences in terms of the throughput vs. energy consumption trade-off; and any proposed solution should be backwards-compatible, given the large number of legacy 802.11 devices already present in existing networks.
