This paper investigates the use of ultra-wideband (UWB) radio for communication in industrial wireless sensor networks (WSNs). OpenWSN is an open-source IPv6 mesh network protocol stack based on IEEE 802.15.4 time slotted channel hopping (TSCH). We adapted OpenWSN to operate an UWB physical layer based on the DecaWave DW1000 UWB transceiver. Experiments were conducted in an industrial steam heating...
It is often assumed that a multi-robot network is connected initially. However, it doesn't agree with the actual case that robots are randomly placed in an unknown environment. This paper explores a control algorithm combined artificial potential field function with the virtual leader in wireless sensor network environment to control the connectivity of a multi-robot system, even initial network is...
Random Network Coding relies on using random codes at nodes for multicast or in cast networks. In random network coding, interior net- work nodes independently choose random linear mappings from inputs to outputs. The effect of the network is that of a transfer matrix from sources to receivers. To recover symbols at the receivers, we require sufficient degrees of freedom - an invertible matrix in...
Nowadays, the healthcare market keeps growing with an increasing aging population. As a promising technology, a body area network (BAN) consisting of biomedical sensors across a human body can gather vital life signals such as electrocardiogram (ECG), pulse, and blood pressure to facilitate effective diagnosis. The BAN can be further integrated with existing wireless infrastructure to offer mHealth...
With the application of wireless sensor networks, many applications not only have ease of installation, reliable data transfer, short-range operation, and extremely low cost and reasonable battery life, whilst maintaining a simple and flexible protocol, but also should have high confidentiality. So the research of the security of the IEEE 802.15.4 is becoming very important. The IEEE 802.15.4 specification...
In the environment of wireless and pervasive computing, wireless storage can provide flexible data access function, data transfer, data collection, and information services, etc. The paper proposes the architecture of wireless storage system, discusses wireless storage system key technologies, and gives performance analysis of it. Later, the paper illustrates related question and some algorithms,...
With recent technological advances in smart sensor platforms, structural condition monitoring implementations based on Wireless Sensor Networks (WSNs) have received considerable attention. Modal identification is an integral step in many structural condition monitoring systems. However, accurate time synchronization is not always possible, leading to incorrect identification of the mode shapes. Although...
