Abstract
The integration of unmanned aerial vehicles (UAVs), or drones, with Wireless Sensor Networks (WSNs)
has been a successful solution to improve real- time monitoring in military operations, mainly in the
border area. WSNs and UAVs, or drones, have been utilized to improve real- time monitoring in military
operations, mainly in border areas. The model utilizes advanced defence grade sensors, such as LiDAR
for accurate object detection and topography mapping and magnetometers to detect anomalies in the
magnetic field that would indicate hidden metallic threats or buried activities. By adding blockchain
technology to the communication infrastructure, the system provides tamper- proof, transparent, and
decentralized storage of sensor data and shields against unauthorized access and manipulation. This
chapter shows some simulation results and threat analysis demonstrates the immunity of the model against
cyber- attacks and performance in ensuring trust in defence surveillance operations.
