Abstract

As more and more wireless systems are being deployed, it is becoming increasingly important for these systems to be able to effectively manage and use their resources to satisfy system demands and operational requirements.  The typical way of handling this task is to come up with a conservative model of the system and design the protocols of interest using a one-time optimization around the assumed system model.  However, because a static system model will not always match the real-world scenario, this approach can lead to under-utilization of available resources when conditions are good and catastrophic failures when conditions are bad.  In our work, we take an alternate approach by avoiding predetermined models whenever possible, instead relying on network devices to observe and learn the state of the system dynamically, making the system self-aware.  By enabling this awareness, the network itself can now adapt to changing conditions, varying resources, and external events.  In this talk, we present two of our ongoing projects that make use of this awareness property to enable self-healing properties.  First, we present our work on developing inference-based adaptive anti-jamming algorithms that allow software-defined radios to modify physical layer parameters in response to changing network and attack conditions.  Second, we present our work on providing self-healing Smart Grid communications in disaster or outage scenarios by bootstrapping a temporary wireless mesh network infrastructure to relay grid health data to a system operator for diagnostic purposes.
