Information freshness is crucial for time-critical IoT applications, since stale information will significantly affect the reliability and accuracy of decisions. This paper investigates the dynamic power control policy for IoT networks to optimize th

Age of information (AoI), a notion that measures the information freshness, is an important performance metric for real-time applications in Internet of Things (IoT). With the surge of computing resources at the IoT devices, it is possible to preproc

Node similarity, which is usually released in the form of a matrix, provides the basis for network analysis. However, directly releasing node similarity matrix may entail privacy risk. More concretely, the sensitive network structure implied in node

In this paper, we study the path planning for autonomous inspection with multiple UAVs in a certain area to minimize the maximum flight distance of the UAV. Particularly, the UAVs are dispatched from the same depot to visit all inspection points, and

At present, attitude estimation and control are thecore issues of drones. Euler Angle method, direction cosine method and quaternion method are commonly used for attitude measurement. Because the first two algorithms have angles to solve singularitie

Aiming at the security problem of cooperative robots, this paper presents a low cost collision detection algorithm without torque sensors. In this method, the collision can be detected with the sampling torque and the dynamic model. First, the relati

This article deals with the boundary feedback control of freeway traffic which is modelled by Aw-Rascle traffic flow model. By means of a Riemann invariants approach, we deduce stabilizing control laws of a single freeway segment. The stability condi

In the traditional SLAM framework, the state estimate is updated at a fixed frequency. However, such an approach can be inefficient because there is no need to update the state estimate when the deviation between two sequential estimates is within th

In this paper we present an approach for modeling and control of the unsteady flow over a circular cylinder at a low Reynolds number (Re = 60). Actuation is achieved by rotating the cylinder and the measured variable is the vertical velocity at a spe
