How to Lower Congestion With Cross-Layer MPR-PHY/MAC Design?

In this paper, the authors introduce a cross-layer design between PHY and MAC for Multiple Packet Reception (MPR). Based on the simulation results, three phases of operation has been identified for MPR-PHY/MAC design depending on the offered load to the network. The design is suitable for multihop ad-hoc networks. The heterogeneous nature of the colliding packets in multi-hop ad-hoc networks, both in size of the packets and the arrival times of the packets, requires a sophisticated design to enable MPR. MPR can resolve congestions in a multi-hop network and improve the Goodput of the network.
