Cross-layer Modeling and Analysis of Multihop Tactical Networking in Convoy Topology

In this paper, we develop a framework for studying the performance of guaranteed and best-effort data delivery services over wireless tactical networks with multiple relays and multiple clusters. In particular, we apply the analysis technique to a convoy topology and incorporate practical models for narrowband VHF radios and propagation to evaluate the network performance. The numerical results have demonstrated the performance tradeoffs between throughput and efficiency/robustness over a wide range of radio modes and network configurations. These results lead to approaches for wireless networking optimized for tactical radios in terrestrial environments.
