The packet radio network developed at the Stanford Research Institute—known as PRNET—was building on the work of the first wireless packet network, ALO-HAnet, which was developed in 1971. Whereas ALOHAnet was using only fixed terminals to wirelessly transmit data, the goal of PRNET was to create a network comprised of fixed and mobile terminals. In this sense, the project was successful: PRNET was able to exchange data with ARPANET in one of the first instances of internetworking.

The presented flood management system offered reliable and comprehensive reports that were not only beneficial but also vital in coordinating rescue and disaster mitigation. Its applicability can be expressed as follow:Reliability: Flooding incidents were primarily detected from RS data of the actual areas. They were collaborated by notifications submitted by flood victims and verified against other various sources by the authorized officers. Depending on verification stages, users upon accessing unified flood reports were always made aware of levels of data integrity.Timeliness: In addition to intermittent reports made by conventional news broadcasting platforms, flood victims and interested parties could constantly query the detailed updates on flood incidents, both historically and as they currently happened, via ubiquitous online platforms.Completeness: The information compiled by the system was comprehensive, both quantitatively and qualitatively. The resultant reports pinpointed flooding location with its extent and informative details, including photographs of surrounding areas, etc. According to our survey on user reflections, officers in charge acknowledged that the offered information played the critical roles in devising, executing, and managing disaster mitigations.Versatility: Thanks to web-based frameworks, the proposed internetworking system was operable on a range of devices and platforms connected to the internet. This has not only enabled greater involvement from the public, but also strengthened compilation of flooding data.
