In this paper, we investigate the energy-delay tradeoff (EDT) problem to reduce energy consumption while ensure packet delay performance for wireless-backhauling ultra-dense network (UDN). We formulate the EDT problem as a cost minimization problem to find the optimal base stations (BS) sleeping ratio for sleeping mechanism. To solve the problem, a dynamic gradient descent iteration algorithm is used to obtain a locally optimal sleeping ratio. We prove it can converge to the global optimal BS sleeping ratio. The impacts of BS sleeping ratio on EC and packet delay are investigated and validated by simulation and numerical results.
