ABSTRACT
One of the major shortcomings in IoT/sensor networks is the finite energy supply available for computation and communication. To circumvent this issue, energy harvesting has been proposed to enable embedded devices to mitigate their dependency on traditional battery-driven power source. However, energy supply due to energy harvesting often varies, leading to nodes crashing due to energy exhaustion, with application(s) losing their state. Efficient state checkpointing in non-volatile memory (NMV) has been proposed to enable forward progress, albeit at the expense of significant overhead (viz., energy and time). In this poster, we show preliminary results that, for a certain class of applications, state checkpointing may adversely affect the performance of the applications. This is different from checkpointing in traditional distributed systems, where the network topology is generally assumed to be stable.

A survey on program-state retention for transiently-powered systems
AbstractLow-power small-scale embedded sensing systems employing batteries generally impose high maintenance costs. To enable maintenance-free operation, they are powered from energy harvested from the environment thus making them batteryless. ...
A fully informed model-based checkpointing protocol for preventing useless checkpoints
Checkpointing and rollback recovery are widely used techniques for handling failures in distributed systems. When processes involved in a distributed computation are allowed to take checkpoints independently without any coordination with each other, ...
Poster: Compiler-assisted Automatic Checkpointing for Transiently-powered Embedded Devices
EWSN ’17: Proceedings of the 2017 International Conference on Embedded Wireless Systems and NetworksWe present compiler-assisted automatic checkpoint strategies to allow transiently-powered embedded sensing devices efficiently save the system’s state onto non-volatile memory before energy is exhausted. Our solution operates at compile-time with no ...
