The present work proposes a power management infrastructure for WSN, with support for heterogeneous, concurrent applications that need to preserve their status during deep-idle periods.

Abstract

The present work proposes a power management infrastructure for WSN, with support for heterogeneous, concurrent applications that need to preserve their status during deep-idle periods. There are two main original contributions: i) the definition and implementation of an integrated and general power management infrastructure, transparent to the end user and supporting heterogeneous concurrent applications, ii) a rigorous model for the optimal choice of the power management policy, considering also set points at the lowest possible power state (power-off) with no memory retention. The power management infrastructure is based on the framework proposed in a previous work and this paper details the architecture and the interaction of its core modules. The whole system has been implemented on a prototype version of the PoliNode infrastructure and Miosix operating system. Results show energy gain up to 98%, varying with the period and size of the applications
