Using UAVs to Secure Linear Wireless Sensor Networks

摘要

A Linear Wireless Sensors Network (LSN) is a sensor network model used for monitoring linear structures such as oil, gas, and water pipelines. This type of network depends on the information sent from one node to another in a sequence. As a result, a failure or attack that occurs at any node may isolate some nodes from the network, which will affect the reliability of the entire network. In this situation, the sensed data cannot be delivered from the isolated nodes. This paper, proposes a solution for this issue. This solution uses Unmanned Aerial Vehicles (UAVs) to mitigate the impact of failed nodes and increase the reliability of the network. UAVs are sent to specific locations in a faulty LSN to provide communication relays for some parts of the network. This paper develops, evaluates, and compares different allocation strategy models for UAVs on a LSN to increase the sensing coverage. The developed allocation strategies are evaluated and compared using a simulation environment.
