Abstract [en]

Wireless sensors networks are used in a variety of environments ranging from environment

monitoring such as humidity and temperature, to environments like patient monitoring, habitat

monitoring etc. Sometimes sensors are deployed in inaccessible or hazardous places, and they

are battery operated; recharging or changing the sensor’s battery is almost impossible.

In such scenarios, where the battery can not be recharged or changed, it is crucial to know in

advance how long the battery will last so that the old sensor node can be replaced by a new

one. Normally, in order to effectively utilize the battery the components of a wireless sensor

node are turned off when not needed.

This paper presents an in-depth analysis of the importance of switching sensor node

components, and its impact on the life time prediction. A new energy model is presented

which caters for the current and time consumed in switching from one mode to another. A

comparison is made between scenarios where current consumption while switching is catered

with the one where it is not catered. This was achieved by using on chip fuel gauge, with

some limitation, which was verified by using digital multimeter.
