Survey on Tracking Methods for a Wireless Sensor Network
Introduction
Wireless Sensor Networks (WSNs) have gained significant importance in recent years due to their wide range of applications in various fields such as environmental monitoring, healthcare, and smart homes. One of the key challenges in WSNs is efficiently tracking the movement of objects or individuals within the network. This survey aims to explore the various tracking methods used in WSNs and evaluate their effectiveness in real-world scenarios.
Problem Statement
The tracking of objects or individuals in a WSN poses several challenges such as limited resources, communication constraints, and energy consumption. Current tracking methods may not be suitable for all scenarios and may not provide accurate or real-time tracking information. Therefore, there is a need to explore new tracking methods that can address these challenges and provide reliable tracking capabilities in WSNs.
Existing System
Existing tracking methods in WSNs include Time-Based, Range-Based, and Hybrid methods. Time-Based methods rely on the time taken for a signal to travel from the sensor node to the object, while Range-Based methods use the signal strength or angle of arrival to estimate the distance between the object and the sensor node. Hybrid methods combine both Time-Based and Range-Based techniques to improve tracking accuracy.
Disadvantages of Existing System
While existing tracking methods in WSNs have shown promise in certain scenarios, they also have several limitations. Time-Based methods may suffer from synchronization issues and may not be suitable for dynamic environments. Range-Based methods may be susceptible to signal interference and may not provide accurate distance estimation. Hybrid methods may require complex computations and may not be energy-efficient.
Proposed System
The proposed tracking method for WSNs aims to address the limitations of existing methods by utilizing a combination of Time-Based, Range-Based, and Machine Learning techniques. The proposed system will leverage the power of Machine Learning algorithms to predict the movement of objects or individuals within the network based on historical data and sensor readings.
Advantages of Proposed System
The proposed tracking system offers several advantages over existing methods. By utilizing Machine Learning algorithms, the system can adapt to changing environments and improve tracking accuracy over time. The system can also optimize energy consumption by intelligently selecting the most appropriate tracking method based on the current network conditions. Additionally, the system can provide real-time tracking information and alert notifications to users.
