“…In this methods the localization is performed based on strength of Wi-Fi [17] or RFID [18] radio signal. A. Dobîrcău, et al [19] in order to fit their system to IoT paradigm use low powered Wi-Fi RFID active devices, which send gathered information to an access point coupled to Internet. An interesting concept presented by Matteo Faraone, et al allows to localize patient inside a room without a need to wear any device just by analysing RSS disturbance between sensor rows, evenly distributed on each wall of the room [20].…”

Wireless sensor networks, WSN, for which development has begun by military applications, are nowadays applied to all human activities; e.g. in medicine for patience monitoring or to reduce the effects of disasters. Therefore, the WSNs area has been also one of the emerging and fast growing scientific fields. Increasing interest of WSNs is even caused by equally intense growth of interest in the Internet of Things domain, IoT, in which WSNs constitute a significant part. These reasons have brought about developing low cost, lowpower and multi-function sensor nodes. However, the major fact that sensor nodes run quickly out of energy has been an issue and many energy efficient routing protocols have been proposed to solve this problem. Case study presented in this paper concern design of WSN in IoT concept from system lifetime perspective. A hierarchical routing technique, which shows energy efficiency, has been validated. Simulation results show that chosen technique prolongs the lifetime of the WSN compared to other investigated clustering schemes. The advantages of this method are validated by comparative studies.

“…Compared to traditional IEEE 802.11 technology, IEEE 802.11n has the following characteristics: 1) MIMO technology; 2) channel bonding, support 20/40 MHz channel; 3) MAC layer frame aggregation. Paper [5,6,7] design some IEEE 802.11n-basedmethod and devices to achieve high transmission rate, but due to the target of these the indoor applications or low-power designs, their transmission power are limited, which cause limited transmission distance and difficulty in mining use. To solve above problems, this paper designs and implements a mining high-power IEEE 802.11n wireless access point, its physical layer link speed is up to 300Mbps, maximum transmitting power support up to 27dBm.…”

This paper designs and implements an IEEE 802.11n based mining high power access point to improve the disadvantages of low throughput, low communication distance which are met in current mining communication systems. By adding high power design to transmitting and receiving path, this design can get over more than 190Mbps throughput in lab testing, and can achieve more than 2km outdoor communication distance. Test results show that the mining high power access point is more suitable for mining application.
