Designing Primary Responder Applications with Web Services in a Hostile Environment

Software products used by primary responders to critical situations in remote places need access to real-time data with little user involvement in a hostile environment. Web services provide a mechanism of obtaining this information but their varying consistency and cost require the developer to design software capable of operating under a variety of agency constraints and data availability scenarios. Adding to this problem is the unreliability of network connections and slow best-case network speed when the product is used in isolated places. The complexity of a critical situation poses the software with a dynamic set of priorities to further complicate the problem. A flexible architecture model and pre-deployment prioritization scheme is proposed that will allow a developer to design a product tailored to agency-specific requirements and can choose the best path to the needed data based on the system and situation status.
