Cross-layer mechanisms are often proposed for coping with performance issues in mobile ad hoc networks (MANETs). The concept behind this technique is for each protocol layer to be enhanced to exploit information produced by other layers so as to optimize network-wide operations. However, the need for a new interaction paradigm inside the protocol stack has to be balanced against the need for layer separation that allows for easy development, maintenance and integration with existing systems. Tactical networks are a type of MANET characterized by limited mobility and low bandwidth for which efficiency and performance are not just desirable, but critical for successful operations. Such networks are also characterized by strict security requirements, which can subject them to excessive bandwidth and processing burdens. In this paper, we argue that network security and performance could be improved in tactical networks through cross layer design. A cross-layer architecture is described that maintains a clean horizontal interface between layers, but also allows layers to coordinate cross-layer information through a vertical publish-subscribe interface. We explore this architecture through its application specifically to the performance and security of tactical networks.
