Abstract Multiple-Input Multiple-Output (MIMO) communications have shown great promise in providing high spectral efficiency for wireless ad hoc networks. In this paper we study the problem of joint routing, scheduling, power control and bit rate selection in MIMO-based ad hoc network with the goal of maximizing the system throughput that satisfies a given end-to-end traffic demand. We formulate this cross-layer optimization problem as a linear programming problem. It is well known that the scheduling problem arising in wireless network is NP-hard due to the exponential optimization space. Accommodating MIMO links in this work greatly increases the computation complexity. The cross-layer optimization problem can be solved by applying an iterative approach proposed and the original problem is decomposed into subproblems and solve them iteratively. Numerical results are given to validate the solution.
