Special Issue Information

Dear Colleagues,

Presently, sensing and sensors are core parts of enlarging the human understanding of natural phenomena. The horizon of human understanding expands through deploying massive amounts of sensors and sensor networks. Of course, the success of artificial and deep learning techniques heavily depends on the data gathered from the sensors and, at the same time, the deep learning provides us with an easy way to analyze and understand the sensor data. Sensors or sensor systems are normally deployed in remote areas, with small-size batteries and for multiple cooperative missions. A main question in massively deploying such multiple-objective sensors is how to extend their lifetime, how to enhance their sensing accuracy, how to safely and reliably collect the data, and how to make them more economical. Collaborative and cooperative sensors may be critical to finding the answers to these questions. This Special Issue shall collect research devoted to the development of new methods in the field of cooperation and collaboration in sensors, sensor systems and sensor networks, which especially enable the economic deployment of massive sensors. The list of topics includes, but is not limited to

  • Modelling, Simulation and Evaluation of Collaborative Sensors and Sensor Networks
  • Cooperative and Collaborative Energy Harvesting in Sensor Systems
  • Cooperative and Collaborative Applications in Sensors, Actuators, Metering and Sensing
  • Cooperative LPWAN Systems and Applications
  • Cooperative Signal and Image Processing in Sensor Systems and Sensor Networks
  • Industrial Internet of Collaborative Things and Smart Manufacturing
  • Cooperation and Collaboration in Wearable or Mobile Devices
  • Cooperation and Collaboration between Sensors in Improving Healthcare
  • Throughput and Service Enhancement through Cooperation and Collaboration in Sensor Systems and Sensor Networks
  • Design and Deployment of Cooperative Multi-objective Sensors
  • Cooperation and Collaboration Schemes between 5G Mobile Terminals
  • Cooperative and Collaborative Chemical and Gas Sensors, Microfluidics, Biosensors, Optical Sensors, Temperature, Mechanical, Magnetic Sensors, and Acoustic and Ultrasonic Sensors

Heterogeneous Bistatic Radars (BR) have different sensing ranges and couplings of sensing regions, which provide more flexible coverage for the boundary at complex terrain such as across rivers and valleys. Due to the Cassini oval sensing region of a BR and the coupling of sensing regions among different BRs, the coverage problem of BR sensor networks is very challenging. Existing works in BR barrier coverage focus mainly on homogeneous BR sensor networks. This paper studies the heterogeneous BR placement problem on a line barrier to achieve optimal coverage. 1) We investigate coverage differences of the basic placement sequences of heterogeneous BRs on the line barrier, and prove the optimal basic placement spacing patterns of heterogeneous BRs. 2) We study the coverage coupling effect among adjacent BRs on the line barrier, and determine that different placement sequences of heterogeneous BR transmitters will affect the barrier’s coverage performance and length. The optimal placement sequence of heterogeneous BR barrier cannot be solved through the greedy algorithm. 3) We propose an optimal BRs placement algorithm on a line barrier when the heterogeneous BR transmitters’ placement sequence is predetermined on the barrier, and prove it to be optimal. Through simulation experiments, we determine that the different placement sequences of heterogeneous BR transmitters have little influence on the barrier’s maximum length. Then, we propose an approximate algorithm to optimize the BR placement spacing sequence on the heterogeneous line barrier. 4) As a heterogeneous barrier case study, a minimum cost coverage algorithm of heterogeneous BR barrier is presented. We validate the effectiveness of the proposed algorithms through theory analysis and extensive simulation experiments. Full article
