Abstract
Multiple Input - Multiple Output (MIMO) systems use multiple antennas to exploit the multipath available in wireless channels and significantly improve communication performance. The use of multiple antennas open a multitude of dimensions to optimize performance based on application, mission and environments. Tactical networks impose additional challenges like mobility, jammers and distributed operation. In this paper we present the design of a Media Access Control (MAC) protocol, called LiSL/M, which optimizes the performance of networked tactical MIMO systems. LiSL/M is an adaptive and opportunistic distributed protocol that schedules links dynamically based on interference, traffic and channel condition. We also discuss our experiments with interfacing accurate MIMO propagation and physical layer models implemented in MATLAB(R) with QualNet(R) network simulator. LiSL/M simulation results show significant 2-3 times better network performance in scenarios envisioned for Future Combat Systems (Lakehurst scenario).
