Link Scheduling in Cooperative Wireless Networks

In this paper the authors propose link scheduling algorithms for a wireless network that employs different modes of cooperation at the PHYsical layer (PHY). In addition to a direct transmission, a cooperative transmission through a relay and cooperative transmission through Physical Layer Network Coding (PLNC) can also be employed by a network node. The physical interference model is extended to reflect the aggregate Signal to Interference and Noise Ratio (SINR) at a node for all the cooperative schemes. With the proposed interference model not all concurrent transmissions are considered as destructive but their precise impact depends on the selected mode of cooperation.
