Throughput Optimization in Multi-Hop Wireless Networks With Random Access

This paper investigates cross-layer design in multi-hop wireless networks with random access. Due to the complexity of the problem, the authors study cross-layer design with a simple slotted ALOHA Medium Access Control (MAC) protocol without considering any network dynamics. Firstly, they study the optimal joint configuration of routing and MAC parameters in slotted ALOHA based wireless networks under a signal to interference plus noise ratio based physical interference model. They formulate a Joint Routing and MAC (JRM) optimization problem under a saturation assumption to determine the optimal max-min throughput of the flows and the optimal configuration of routing and MAC parameters.
