Title
Joint Congestion Control and Power Control With Outage Constraint in Wireless Multihop Networks.
Abstract
We consider the problem of joint congestion control and power control with outage constraint in an interference-limited multihop wireless network. We transform the original nonconvex 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. We 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. Numerical results show that both schemes have nearly identical performance and outperform the conventional scheme.
