Power aware scheduling for Adhoc Sensor Network nodes

Abstract

Adhoc Sensor Networks are being considered for many novel applications. There are many challenges while designing the sensor based adhoc network but main constraint is the power consumption done by the sensor nodes. Many solutions have been proposed to save the power of the senor nodes which are based on routing and other methodology. Most of the studies have considered switching off of the radio to save power under various routing conditions and measured throughput of network traffic. Another major task of sensor nodes is to sense the environment or some parameters which can be based on application needs implemented through various tasks and their scheduling. A mix of realtime, critical and non realtime task scheduling has been implemented for a micro-controller having various power saving modes and it is shown that it can provide significant saving of power for the sensor node.
