Control of Video Stream Transmission in a Flying Ad Hoc Network

Abstract

This article delves into the issue of localizing sensor nodes within a wireless sensor network (WSN). Sensor nodes are pivotal for information gathering, communication, and data transmission in WSNs, and their strategic placement is crucial for network operation. However, in scenarios where sensor nodes are randomly positioned, such as remote locations, ascertaining their locations becomes paramount for BSS applications. The proposed solution to the localization predicament involves establishing inter-node distances and subsequently computing relative positions. Two primary methods for distance determination are examined: signal strength-based measurement and signal reception time differential analysis. These approaches are relatively straightforward and do not demand substantial computational resources, rendering them appealing for practical implementation in real-world scenarios. The conducted studies on the proposed distance estimation methods demonstrate their ability to address the localization challenges encountered in wireless sensor networks. By utilizing these approaches, not only the efficiency and accuracy of localization for sensor nodes can be improved, but it is also possible to ensure the operation of wireless sensor networks under various operating conditions.
