Power Management
Why? Limited energy resources
Allow functionality despite scarce energy resources
Reduce power consumption by sharing tasks with other nodes
![Page 17: Amair Mairaj Ankush Pandit Krutarth Mithawalla Nick Mathew Raman Narayanan](https://reader030.vdocuments.us/reader030/viewer/2022032607/56649ece5503460f94bdb850/html5/thumbnails/17.jpg)
Solution
Low threshold for migration Distribute when migration occurs
without execution until energy resources fail
In case of catastrophic failures, spare node could restart execution if the hand-off signal never arrives.
