Joint Congestion Control and Power Control With Outage Constraint in Wireless Multihop Networks

The authors consider the problem of joint congestion control and power control with outage constraint in an interference-limited multihop wireless network. They transform the original non-convex problem into a convex programming problem and develop a message-passing distributed algorithm that can attain the global optimal source rate and link transmit power. This algorithm however requires a larger control message size than that of the conventional scheme, which increases network overheads. They continue to develop a practical near-optimal distributed algorithm that only requires local Signal-to-Interference Ratio (SIR) measurement to limit the size of the message.
