英文摘要：

In order to support cross-layer protocol design of Ad Hoc networks equipped with multiantennas, an analytical model consisted with both PHY and MAC layer based on spatial multiplexing was proposed Using this model, NS2, a general-purpose platform was developed, so that it could simulate cross-layer designed MAC protocol based on spatial multiplexing. Results of theory analysis and simulation show that the modified version of NS2 works well. Simulation results also confirm that, for Ad Hoc networks whose nodes equipping multi-antennas, specific cross-layer protocol design is an efficient method to improve network throughput.
