| Recent advances in embedded computing, networking, and related information technologies have made it feasible to create Instrumented Cyber Physical Spaces (ICPSs) that are technologically cutting-edge and exemplary of highly instrumented spaces of the future. Such ICPSs integrate a variety of sensing devices to create a digital representation of the evolving physical world that can then be exploited by applications for a variety of purposes. The networking landscape of today, especially in Instrumented Cyber Physical Spaces, is characterized by diverse access technologies including cellular, WiFi, Ethernet, MANETs, and ZigBee, and properly managing this heterogeneous networking infrastructure is a key challenge to take full advantage of its many opportunities.;In this thesis, we propose MINA (Multinetwork INformation Architecture), a reflective (self-observing and adapting) middleware approach to realize and manage dynamic and heterogeneous multi-networks in CPS/IoT environments. A novel aspect of MINA is that it embodies an Observe-Analyze-Adapt (OAA) loop to a) achieve a reasonably accurate, centralized global view of the multi-network through the design of novel techniques for overlay structuring, network state collection, b) employ formal methods to perform network state analysis and answer questions in network management domain such as: which nodes are more important and should be protected? and c) take advantage of the global view for adapting multi-network structure by reallocating application flows across networks and proactively planning and deploying additional network resources. For each step in the OAA loop, we have proposed, implemented and evaluated several sophisticated methodologies to achieve certain objectives on the networking simulator platform. To demonstrate the validation of MINA, we designed, implemented and thoroughly evaluated a set of software over multiple networks and platforms. The results shows that MINA actually improves the exploitation of multi-network capabilities. |
