Power Consumption Analysis of Operating Systems for Wireless Sensor Networks

In this paper four wireless sensor network operating systems are compared in terms of power consumption. The analysis takes into account the most common operating systems-TinyOS v1.0, TinyOS v2.0, Mantis and Contiki-running on Tmote Sky and MICAz devices. With the objective of ensuring a fair evaluation, a benchmark composed of four applications has been developed, covering the most typical tasks that a Wireless Sensor Network performs. The results show the instant and average current consumption of the devices during the execution of these applications. The experimental measurements provide a good insight into the power mode in which the device components are running at every moment, and they can be used to compare the performance of different operating systems executing the same tasks.This work was supported by the I+D+i program of the Generalitat Valenciana, R&D Project GV05/043, and Vicerrectorado of investigation, development and innovation of Universidad Politecnica de Valencia PAID-06-06-002-61.
