The most commonly used scheduling scheme to build wireless multi-hop networks is CSMA-CA as off-the shelf IEEE 802.11 radios can be used to easily and cheaply deploy a multi-hop network. However, several researchers have observed that using CSMA-CA with either TCP or without any rate control and pumping data as fast as possible leads to unfair and inefficient throughouts, and even starvation for certain flows. Researchers have explored two different directions to allocate fair and efficient throughputs in wireless multi-hop networks.
