Effect of Localization Accuracy on Battery Consumption of Nodes in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are often employed to work in unattended, unreachable and may be hostile environments where replacing node battery may be an impossible task. The process of knowing the origin of monitored event is called localization. Also sensor node/network lifetime depends strongly on battery lifetime. Due to the fact that replacing batteries manually in the field is impossible, several researches are on to find techniques to prolong the battery lifetime. This work attempts to study the effect of localization accuracy on battery lifetime and hence the network lifetime.
