A 330,000 gate field programmable gate array (FPGA) VS12C fabricated on 0.2μm full-depletion silicon-on-insulator (FD SOI) process is presented and the test results indicate this chip has the lower power and higher tolerance to radiation compared with Xilinx radiation-hardened XQVR300 chip implemented on 0.22μm epitaxial silicon. This paper demonstrates the benefit of the FD SOI technology on low...
In this paper, we proposes a multi-gateway nodes data collected routing algorithm based on load balancing(TBLB algorithm) and energy balance, robustness, data forwarding and anti-interference etc, which is multi-gateway nodes-based in wireless sensor network. This algorithm fully takes into account the problem of excessive power consumption when it serves as the data forwarding task, to reduce node...
A large and sudden current called surge current is always induced due to the momentary supply current through a low resistance path to ground when filed programmable gate array (FPGA) power on. This surge current will request the power supply of FPGA to source more current to meet this instantaneous demand or complicate the power management system of FPGA in order to succeed in powering up FPGA. Therefore,...
A novel logic block circuit consisting of two multi-mode logic cells is proposed for the design of a tile-based FPGA fabricated with a 0.5μm SOI-CMOS logic process. Each logic cell contains two 3-LUTs. The proposed 3-LUT based logic cell circuit increases logic density by about 12% compared with a traditional 4-LUT implementation. The logic block can be used in two functional modes: LUT mode and Distributed...
The monitoring system in coal mine has special requirements for data query. Analysis shows that routing in the system should have four features: data-centric routing, supporting query of geographic position, low delay and high reliability of data transmission, robustness of topology. A mobile agent based routing algorithm with mobile sink and a dynamical weight metric which is derived from its current...
Wireless sensor network (WSN) is a novel technology in acquiring and processing information and has been an active research area in recent years. In this paper, firstly, a high reliability routing protocol is designed which is able to rapidly detect the change of topological and routing information of network, choose the best route, recover route when some nodes damaged. Secondly, the basic information...
Wireless sensor network is applied widely in monitoring system of coal mine. An application environment of WSN in coal mine is analyzed to satisfy the data acquirement of mine monitoring. The result of analysis shows that routing protocols applied in coal mine should have four characteristics: data-centric routing mechanism, supporting query of geographic position information, low delay and high reliability...
Due to the special and complicated environment in coal mine, the reliability and energy-efficiency are both the primary issues to be considered during the design of the wireless sensor networks (WSNs) for coal mine. In this paper, we put forward a reliable geographical adaptive fidelity (RGAF) routing protocol, which is based on cluster-unit topology (CUT) for the WSNs in coal mine. RGAF utilizes...
