Abstract
The importance of wireless sensors is increasing day by day due to their large demand. Sensor networks are facing some issues in which battery lifetime of sensor node is critical. It depends on the nature and application of the wireless sensor network and its different parameters (sampling frequency, transmission frequency, processing power and transmission power). In this paper, we propose a new and realistic model to show the effect of energy consumption on a lifetime of wireless sensor nodes. After analyzing the model behavior, we are able to find out the sensitive parameters that are highly effective for lifetime of sensor nodes.
Highlights
The low cost, the low implementation complexity, and the flexibility of wireless sensor networks (WSNs) account for them who are employed in industrial, residential and commercial sectors
We are presenting a new and realistic model, in which WSN energy consumption parameters are discussed in detail that will help to enhance the lifetime of the wireless sensor node
According to Eqn 2, energy consumption of a sensing unit depends on sampling frequency, processing power, sampling duration where LT is a lifetime of node which must be less or equal to the total time
Summary
The low cost, the low implementation complexity, and the flexibility of wireless sensor networks (WSNs) account for them who are employed in industrial, residential and commercial sectors. It is more difficult to replace a battery with hundreds of sensor nodes all the time [2]. This was the main reason which attracted researchers to study a way out to devise a lifetime network for WSNs. The energy is the main limiting factor for a battery life. We are presenting a new and realistic model, in which WSN energy consumption parameters are discussed in detail that will help to enhance the lifetime of the wireless sensor node.
