The Main Objective Of This Paper Is To Study Theimpactofthesensorfieldenvironmentonthelifetimeofthebatteryofthesensornode.Specifically, Temperature, One Of The Environmental Parameters, Is Chosen For The Experimental Studies Undertaken In This Work. The Lifetime And The Power Consumed By The Sensor Node Are Analyzed At Different Temperatures. The Reasons For The Early Death Of The Battery Of The Sensor Node At Lower Temperatures Are Identified. Some Strategies Are Proposed To Overcome The Same. Experimental Results Have Shown The Life Of The Sensor Node Is 18% More When The Proposed Techniques Are Used. Article Received: 10 August 2020, Revised: 25 October 2020, Accepted: 18 November 2020 Introduction Wireless Sensor Networks (Wsns) Have Attracted The Research Community Because Of The Challenges It Has Posed Due To Its Limited Resources. One Of The Vital Resources Of A Wireless Sensor Node Is The Energy Source. A Wireless Sensor Node Is Powered By A Primary Battery. Owing To The Smaller Size Of The Sensor Node, The Size Of The Battery Will Be Smaller, And Hence Available Energy With Which The Sensor Node Operates Will Be Limited. Thus The Life Time Of The Sensor Node Directly Depends On The Life Of The Battery. Further, When The Wsns Are Deployed In Hostile Environments It Is Not Possible To Replace The Exhausted Batteries. Therefore There Is A Need To Use The Energy Of The Battery Minimally To Increase Its Life. Specifically, When The Wsns Are Deployed In Colder Environmental Conditions, Experimental Investigations Have Shown That The Sensor Node Lifetime Has Been Shortened. Their Reduced Life Is Mainly Attributed To The Untimely Death Of The Battery That Drives The Sensor Node. The Strategies Adopted In This Paper Have Resulted In A Sensornodelifetimeenhancementof18%. The Lower Mobility Of Ions In The Electrolyte At A Lower Temperature, Rate Capacity Effect, And Recovery Effect Of The Battery Are Found To Be The Major Causes For The Early Drain Of The Battery. The Reduced Mobility Of The Ions Will Appear As Increased Internal Resistance Of The Battery. Therefore, When The Load Is Connected To The Battery, Apart Of The Power Delivered By The Battery Will Be Dissipated By The Increased Internal Resistance Of The Battery. This Results In A Quick Drain Of The Battery.
