Wireless Sensor Networks present several advantages when compared to wired ones, among them, the low consumption and simplicity of installation. In some cases, energy consumption may be so low as to allow the use of energy harvesting techniques, as in the case of EnOcean protocol. In other networks, it is necessary to meet specific requirements, such as in industrial ones, where communication must...
The wireless sensor networks (WSN) are gradually gaining attention because it is a key technology for the Internet of Things. For most of these networks, the data is usually collected in a manual way, by removing a memory unit or connecting the collector node to a personal computer. This is a constraint, because it demands the manipulation of the collector radio by the operator, which consists in...
Many wireless communication protocols based on the IEEE 802.15.4 standard have been developed for industrial process monitoring and control. Among the various standards available, the Wireless HART protocol is the most promising and has been largely used. It becomes necessary to utilize a protocol analyzer during development, debugging, and testing steps of anew Wireless HART field device. Among the...
The price and size reduction of computational devices have increased the number of areas where human-operated equipments are replaced by autonomous and autoconfigurable devices. The IP protocol has taken place in industrial and home automation, specially in wireless applications. It allows applications to use interoperable communication strategies commonly used in the computer networks as the Web...
