In this paper, we discuss the implementation of a CrOss-layer Based testbed with Analysis Tool (COmBAT). COmBAT is developed to enable the design and development process of next-generation cross-layer based wireless communication technologies for tactical ad-hoc networks. The COmBAT architecture comprises of two major components; (i) Adaptive cross-layer (AXL) framework implemented on each node in the testbed and (ii) NEtwork Analyzing Tool (NEAT) that provides a graphical interface for users to track and analyze network metrics as well as provide a single seat control over the network parameters on-the-fly. In this paper, we discuss the design and implementation of these components in detail and demonstrate its feasibility by implementing three cross-layer based algorithms on COmBAT using a nine node ad-hoc network. The results validate the modularity and adaptability of COmBAT and demonstrate how COmBAT can be used to develop as well as refine current and future cross-layer algorithms providing a feasibility study that lends itself to the transition of theoretical network research from testbed to relevant military hardware.
