The Airborne Network Definition (AND) project had the goal of creating and testing a robust, efficient network
architecture networking all elements of the battlefield. This effort has since been generalized to fit the goals of
the Mobile Edge Network System Architecture (MENSA) effort. The network is designed to be self-contained,
attaching to fixed backbone infrastructure whenever possible. The fundamental building block of the architecture
is the Small Combat Network (SCN), which integrates heterogeneous ground and air platforms, facilitating collaborative
applications such as Blue Force Tracking, Cooperative Sensing and Targeting. The architecture uses
the concept of an IP core to network unlike domains (radio types) and to connect the SCN to the backbone
and the Global Information Grid (GIG). This paper describes the requirements of the network and outlines the
technical design of the SCN architecture. We present step-by-step descriptions of a communication on the SCN
which highlights some of the key features of the architecture. We present results of a simulation that applies our
proposed architecture to realistic warfighting scenarios. Results show that the architecture enables cooperative
applications and point to future work that will design and evaluate a deployable AN network architecture.
This paper investigates the performance of single and multiple TCP connections sharing a bandwidth-delay link. The link employs block-based error correction codes ECC, along with interleaving which is first shown to affect the performance of a single TCP connection. We examine impact of using ECC and interleaving on multiple connections on an ideal two-state fading channel model. Results are obtained by numerical simulation of both single and multiple TCP connections over the channel. Single TCP connection results show that the delay introduced by interleaving significantly affects TCP performance on a lossy channel. Without ECC, the aggregate channel utilization of multiple instances of TCP is higher than that of a single TCP instance. We find that this advantage dissipates when significant ECC is introduced.
