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 (NVM) has been pro- posed to enable forward progress, albeit at the expense of significant overhead (viz., energy and time). In this paper, we show that, for a certain class of applications, state check- pointing may adversely affect the performance of the applications. This is different to checkpointing in traditional distributed system where network topology is generally assumed to be stable.
