Secure, low-power, IP-based connectivity with IEEE 802.15.4 wireless networks

چکیده
Industrial instrumentation makers have repeatedly grappled with questions of how and when to utilize IP-based interconnects – which have in their favor widespread commercial adoption, rapid development cycles, and broad interoperability – in place of their more traditional, often proprietary industrial counterparts. Ethernet led the way as an alternative to RS-485 and other multidrop buses, and many industrial standards, including BACNet, LonTalk, Common Industrial Protocol (CIP), and Supervisory Control And Data Acquisition (SCADA), introduced an IP option utilizing either TCP/IP or UDP/IP over Ethernet. However, IP’s ease of integration and broad interoperability raised some fears about reduced barriers to attack.

Demo Abstract: Self-configuring and IP-enabled Low Rate Wireless Personal Area Networks based on 6LoWPAN and IEEE 802.15.4
Low rate and low power personal area networks (LR-WPANs) which use IEEE 802.15.4 physical and MAC layers at the lower layers of the protocol stack, have been conceived for sensor network applications for their inner characteristic of reduced size, power saving and proximity coverage range. In these application scenarios, the ZigBee protocol stack is often used to create closed, ad hoc environme...
متن کاملAn Energy Efficient Clustering Method using Bat Algorithm and Mobile Sink in Wireless Sensor Networks
Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...
متن کامل6 LoWPAN : Incorporating IEEE 802 . 15 . 4 into the IP architecture
Executive Summary IP for Smart Objects seeks to extend the use of IP networking into resource-constrained devices over a wide range of low-power link technologies – IEEE 802.15.4 represents one such link. Extending IP to low-power, wireless personal area networks (LoWPANs) was once considered impractical because these networks are highly constrained and must operate unattended for multiyear lif...
