On reduced time fault tolerant paths for multiple UAVs covering a hostile terrain
We present a method for finding reduced time coverage paths of multiple UAVs (Unmanned Air Vehicles) monitoring a 3D terrain represented as height fields. A novel metric based on per time visibility is used that couples visibility gained at a terrain point with the time spent to reach the point. This coupled metric is utilized to form reduced time paths by maximizing the visibility gained per u...
متن کاملEnergy-Efficient and Fault-Tolerant Positioning of Multiple Base Stations
As the nodes have limited battery power in Wireless Sensor Networks (WSNs), energy efficiency and fault tolerance should be the two major issues in designing WSNs. However, previous studies on positioning base stations (BSs) in WSNs are focused on energy efficiency only. Yet, mission-critical applications like emergency medical care systems should be guaranteed continuous services considering f...
متن کاملSelf-Organising UAVs for Wide Area Fault-tolerant Aerial Monitoring
This paper describes an algorithm for the coordination of a flock of multirotor UAVs which cooperate in performing a wide area monitoring mission. The key characteristics of the proposed approach are the self-organising ability and the decentralisation. The flock has the basic task of covering a certain area of terrain and is able to self-organise in order to (i) find a coverage of the area whi...
متن کاملCooperative Fire Monitoring using Multiple UAVs
This paper discusses the possibility of using multiple low-altitude, short endurance (LASE) Unmanned Air Vehicles (UAVs) to cooperatively monitor a forest fire. The UAVs will individually track the fire’s perimeter by means of an on board infrared sensor. Using a decentralized cooperation scheme the UAV team will collect data and upload it to a base station. Simulation results are presented tha...
متن کاملA Hybrid Fault Tolerant Approach for AES
In this paper, a lightweight hybrid fault tolerant approach for AES, which is based on the integration of the algorithm based fault tolerant (ABFT) technique and the fault tolerant technique for s-box byte substitution operation is proposed. Two versions of scheme are presented to satisfy different application requirements. The first general version scheme can detect single error for the whole ...
