Multiple-input and multiple-output (MIMO) technique can significantly improve\ntransmission reliability and bandwidth efficiency in wireless networks.\nHowever, many upper layer aspects of MIMO links, especially in mobile networks\nwith heterogeneous antennas and strong interference environments,\nneed further investigation. In this paper, we study its impact on medium\naccess and network capacity. Since MIMO links can enhance physical layer\ncapacity and co-channel interference suppression that affects network access\nscheduling directly, we develop a capacity-optimized access scheduling control\n(COASC) scheme for mobile ad hoc networks (MANETs) with MIMO\nlinks. We formulate the distributed scheduling taking the key of optimization\ninto design to improve the network capacity and transmission reliability. Simulation\nresults are presented to show the effectiveness of the proposed\nscheme.
