In the paper, we illustrate the importance of the concept of mobile network computer from a technological perspective. Because of the usefulness of mobile network computers, with the growth of the Internet of things, mobile network computers may include not only TV box audio-visual equipment, wireless household appliances, and mobile communication equipment, but may also include devices such as intelligent...
Tag collision occurs easily when the multiple tags respond to the same reader query simultaneously over a shared wireless channel. The solution of tag collision is a significant issue in the mobile RFID environment, because of the random mobility of tags. For the purpose of object tracking, locating and monitoring, the reader will repeatedly identify the same tags which still stay within its read...
In view of that the existing auction mechanism cannot effectively allocate cloudlet resource, which leads to a low resource utilization rate and social welfare. In this paper, we design a truthful greedy mechanism (TGM) to coordinate the auction of mobile users (buyers) and cloudlets (sellers). TGM consists of the greedy allocation algorithm based on buyer preferences and pricing mechanism, and improves...
In this paper we propose a shared-control based teleoperation design for a dual-arm omnidirectional mobile robot. The robot not only can adapt its motion to environment autonomously, but also move according to the user's remote commands. To achieve this goal, a shared-control scheme for effective remote control of the mobile robot is developed. For tele-presence and remote control, a user interface...
The mechanisms to maintain redundancy are essential to distributed data storage in Unattended Wireless Sensor Networks (UWSNs). To address this challenge, we proposed a novel hybrid scheme, which takes the advantages of both Erasure Codes (EC) and Self-repairing Codes (SRC) to guarantee better security on data storage and redundancy maintenance, and adapt an enhanced location-based pair-wise keys...
This paper presents a mobile manipulation and visual servoing design for a configurable mobile manipulator by using a Kinect sensor. To achieve this goal, an image-based grasping design is combined with a visual simultaneous localization and mapping (vSLAM). The proposed vSLAM method is based on extended Kalman filter (EKF) and a Kinect RGBD sensor. In the manipulator design, the robot arms are designed...
The data collection schemes in wireless sensor network (WSNs), have been intensively studied in the decade yet still a very active area. A number of schemes, such as the multihop data forwarding and the mobile element (ME) gathering, have been proposed. In the majority of the literatures, the full sensing field coverage and network connectivity are usually ignored or assumed to be true. However, such...
