In this paper, we propose a trust-based vehicular platoon crowdsensing scheme, named TripSense, in VANET. The proposed TripSense scheme introduces a trust-based system to evaluate vehicles' sensing abilities and then selects the more capable vehicles in order to improve sensing results accuracy. In addition, the sensing tasks are accomplished by platoon member vehicles and preprocessed by plato...

This paper describes a novel scheme for the fusion of spectrum sensing information in cooperative spectrum sensing for cognitive radio applications. The scheme combines a spectrum-efficient, pre-distortion-based fusion strategy with an energy-efficient censoring-based fusion strategy to achieve the combined effect of reduction in bandwidth and power consumption during the transmissions of the l...

In this paper, we consider reliable cooperative spectrum sensing in cognitive networks under the Spectrum Sensing Data Falsification (SSDF) attacks. One effective method to mitigate the SSDF attacks is the q-out-of-m fusion scheme, where the final decision is based on q sensing reports from m polled users. In this paper, first, we derive the asymptotic behavior of the fusion scheme as the netwo...

In cognitive radio based cooperative sensing systems, some secondary users are likely to act malicious. Such secondary users are called malicious users. An optimal application of Dixon's outlier detection scheme for detecting malicious users in a cognitive radio cooperative spectrum sensing system has recently been termed as the Sliding Window Dixon's test. The Sliding window Dixon's test appli...

In recent years, various sensors are embedded into a so-called smartphone. A human-probe community is paying great attention to a smartpohne as a sensing node because it allows users to participate sensing activity easily. However, on-body localization of a sensor is critical issue if we utilize a smartphone as a sensing platform for human-probe. For instance, acceleration, temperature or humid...

LIGO has an input mode cleaner, which is a 3 mirror resonant cavity. It is designed to let pass through only 1064 nm TEM00 light out of all the frequencies and modes emitted by the Pre-Stabilised Laser. This design involves the position as well as the alignment of the mirrors. Hence, a potential problem becomes to sustain a particular length and alignment of the cavity, given all the disturbanc...

This letter proposes a novel distributed compressed estimation scheme for sparse signals and systems based on compressive sensing techniques. The proposed scheme consists of compression and decompression modules inspired by compressive sensing to perform distributed compressed estimation. A design procedure is also presented and an algorithm is developed to optimize measurement matrices, which ...

We investigate sensing-assisted beamforming for vehicle-to-infrastructure (V2I) communication by exploiting integrated sensing and communications (ISAC) functionalities at the roadside unit (RSU). The RSU deploys a massive multi-input-multi-output (mMIMO) array mmWave. pencil-sharp mMIMO beams fine range-resolution implicate that point-target assumption is impractical, as vehicle’s geometry bec...

In this paper an approach to real-time position correction and environmental modeling based on odom-etry, ultrasonic sensing, structured light sensing and active stereo vision (bin-and trinocular) is presented. Odometry provides the robot with a position estimation and with the help of a model of the environment sensor perceptions can be matched to predictions. Ul-trasonic sensing is capable of...
