We describe a performance comparison analysis of utilizing directional links in tactical MANETs. Performance is measured in terms of the achievable throughput and end-to-end delay. We describe three different alternatives of integrating Network Data Link (NDL) with tactical MANET stack. The three alternatives include integration at the network layer of a Commercial-Off-The-Shelf (COTS) MANET stack using standard OSPF, integration at the network layer of the Wideband Network Waveform (WNW) stack utilizing a mobile extension of OSPF called R-OSPF, and integration at the Mobile Intranet (MI) layer of the Wideband Network Waveform (WNW). Our experiments show the advantage of the third approach over the other two approaches measured both in terms of the achievable throughput and end-to-end delay. In addition, our study highlights major design factors associated with the placement of NDL capable radio nodes in a MANET topology.
