Safe Community Awareness and Alerting Network (SCALE) is a community government/academic/industry partnership effort that aims to deploy, actuate and evaluate techniques to support multiple heterogeneous IoT technologies in real world communities. SCALE2, an extension of SCALE, engages a multi-tier and multi-network approach to drive data flow from IoT devices to the cloud platforms. While devices are used to gather data, most of the analytics are executed in the cloud. Managing and utilizing these multiple networks, devices and technologies is a big challenge that calls for an integrated management. In this context, we propose to leverage a related effort, MINA (Multi-network INformation Architecture), that aims at integrating operations of multi-networks IoT deployments in a hierarchical manner. This paper discusses the mapping of the SCALE2 heterogeneous platforms in the MINA environment and argues for a hierarchical approach to extending and managing community IoT multi-networks. We discuss resilience methods that can be employed at different tiers in the hierarchical architecture. We illustrate examples of how multiple applications can be supported in this heterogeneous setting; example applications include cooperative seismic event detection, mobile data collections for air quality information and assisted living for elders. Finally, we discuss novel research challenges associated with managing multi-network IoT architecture.
