Query: Transparent Recovery of Dynamic States on Constrained Nodes through Deep
  Packet Inspection   Many IoT applications make extensive use of constrained devices which are
characterized by unexpected failures. In addition, nodes could be put offline
temporarily for maintenance (e.g. battery replacement). These incidents lead to
loss of dynamic data that is generated due to the interactions between nodes.
For instance, configuration settings adjusted by sending PUT request to the
sensor will be lost when the node is rebooted. The lost data, which we call
dynamic states, leads to erroneous results or malfunctions of the IoT
application. In this paper, we introduce an intelligent dynamic state recovery
mechanism through deep packet inspection. A State Directory, placed at the
gateway, intercepts every communication between an external device and
constrained devices and stores (or updates) information that is important to
restore dynamic states. When a node reports a reboot, the state directory
replays the packets that generated the dynamic state so that all dynamic states
are restored. We implemented the solution on a non-constrained device that acts
as a gateway to the constrained network and tested the results using Cooja
simulator.
