Dynamic Control Policy for Delay Guarantees in Multi-hop Wireless Networks
This paper considers the dynamic control of stochastic networks for the guaranteed delay with network utility maximization in multi-hop wireless networks. On contrary to single hop case, the delay is difficult to predict in multi-hop scenarios due to their unpredictable traffic pattern and variable queuing time in intermediate nodes. We present here a control policy for joint flow control and scheduling which can achieve high network utility and guarantees delay constraints. In addition, we derive the capacity region of the network under a given delay condition. Simulation results show that the proposed policy achieves near optimal network utility with delay guaranteed compare to exiting algorithms.
