Wireless body area networks (WBANs) have attained increasing popularity as the next generation framework of wearable technologies for human monitoring. Invasive or noninvasive wearable sensors designed in a WBAN are worn to gather vital information. Biofeedback is a recent concept where collected data are used to generate actuation signals in WBANs. Applications can be seen in various areas such as...
Intrabody communications (IBC) is a promising data communication technique for body area networks in biomedical applications. This short distance communication approach transmits signals through body tissue forming a wireless network among on-body sensors. It is defined as one of the physical layers for the new IEEE 802.15.6 or Wireless Body Area Network (WBAN) standard. It is meaningful to investigate...
In the wireless sensor network (WSN), the operation reliability is usually evaluated by processing measured datas at network nodes. As the traditional algorithms exist the problems of the complex calculation and large energy consumption, a method for fault diagnosis of nodes in WSN based on rough set theory (RS) and support vector machine (SVM) is proposed in this paper. In this paper, we collect...
In this paper, taking mobile robot as the research object, the embedded control system is designed adopting PC/104 as host controller, which achieves the link among the expand boards, power module, motor driving module, perception modules, the HCI interface modules and so on; Wireless communication technology in mobile robots is investigated deeply, and then wireless remote control and wireless serial...
This paper presents the design of two types of wideband bandpass filters with different bandwidths for millimeter-wave D-band applications. The proposed filters are implemented on a three-layer structure deposited on a 400-µm silicon (Si) bulk with benzocyclobutene (BCB) as the substrate. The characteristics of the basic structures for these two types of bandpass filters, a square ring resonator and...
This paper presents a novel address assignment algorithm (Adaptive Dynamic Address Redistribution ADAR) and tree-based routing protocol for large-scale uneven Wireless sensor networks (WSNs). The ADAR algorithm can make 16-bit address space used effectively and it also can solve the problem that nodes which want to access the WSNs can not be assigned addresses because of the father node running out...
In mobile ad-hoc networks, the data tends to be intercepted by malicious node when using a single path for transmission. In this paper, we propose a secure routing protocol based on multipath routing technology, namely AODVsec, which divides a data unit into several data pieces and transmits these pieces through different paths. By setting security level on each node, AODVsec limits the maximum number...
Multi-robot coordinated control has been practical. In order to apply multi-robot coordinated control technique in cooperative task processing in a great environment, we should allocate task for robots and the robot should locate itself in the environment. To solve multi-robot task allocation and robot localization problem for coordinated multi-robot in great environment, a wireless sensor network,...
