This work tries to take one step ahead in the interaction within WSNs, proposing an integral web interaction from the end user to the sensor tags in order to take advantage of the IP network technologies during all the data transmission process. In other words, we put each sensor tag www.selleckchem.com/products/mek162.html directly in the Internet as part of the Internet of Things paradigm [11], whereby everything will be interconnected anytime and anywhere.The primary purpose of the current paper is to present the new concept of near field Inhibitors,Modulators,Libraries sensor tags with a web browsing interaction for secure applications. This is done by tunneling the TCP/IP Inhibitors,Modulators,Libraries traffic over a near field radiofrequency technology (NFC), avoiding the use of proprietary protocols and application program interfaces.
As the NFC identification technology is not intended to exchange large amount of data, the problems found so far and the way they have been solved, as well as the advantages of this near field web access approach, will be Inhibitors,Modulators,Libraries shown in the next sections.The remainder of the Inhibitors,Modulators,Libraries paper is organized as follows: Section 2 reviews the basic access modes of sensor monitoring used nowadays and the main wireless technologies used. Section 3 introduces the concept of the proposed sensor tag with a web access. Section 4 presents a summarized explanation of the implementations and the system evaluation of the WebTag. The conclusions of this paper are summarized in Section 5.2.?Access Modes of Sensor Wireless MonitoringSensor wireless monitoring can be analyzed and classified in many ways, but in this section we are going to focus on one specific aspect: the access mode.
Regarding the interaction in sensor wireless monitoring, we can simplify it into two access modes: near field or remote access, depending on where the information is processed. In the first case, a dedicated device (reader) reads directly the sensor data, processes the information and interacts with the end user depending Cilengitide MLN2238 on the application requirements. However, in the second case, the sensor data is retransmitted through the wireless network before it reaches the network gateway, where that data is sent to an upper decision making system. The WSNs use mainly the remote access mode, while the near field mode is more used in classical wireless monitoring.In both cases, the communication process can be divided into two main stages: the former (on the right side of the Figure 1) is carried out when the data is transmitted from the sensor tag to the reader or the network gateway (let’s define it as data acquisition), depending on the access mode. The latter, is done when data is sent upstream from the reader or the gateway node to an upper decision making system or to the Internet (let’s call it data transmission).
