Characterization Framework and Design Patterns for the Disadvantaged User

Many service oriented architecture (SOA) approaches in use today presume the consistent availability of reliable networks and limitless resources. For some department of defense (DoD) and other government users, operating at the tactical edge, who may be disadvantaged in terms of network and resource availability, the current methods of development may not provide them with reliable capability. In this paper, we propose a method for capturing design patterns for the disadvantaged user using the common vocabulary of a characterization framework. We also provide a set of design patterns that minimize technical constraints, and derive the infrastructure requirements needed to implement a selected design pattern.
