Multiple Access Methods utilized to extend Operational Life Time of Wireless Sensor Nodes

Abstract

The power consumption in wireless sensor networks is one of the main issues when designing sensor nodes. Furthermore the available energy density of batteries for a given battery size and the difficulty of recharging possibilities limits the life cycle of sensor nodes. Multiple access methods will help to expand the operational life cycle of sensor nodes by reducing their power consumption. The focus of this work is to evaluate multiples access methods wake-up solutions for wireless sensor applications. A custom demonstration platform to perform theses evaluations and measurements has been developed. The current measurements have shown that multiple access wake-up methods in conjunction with switching of not needed components will extend the life cycle of sensor nodes immense.
