چکیده

This paper presents a kind of message conversion method between wired/wireless hybrid network, aiming at meeting the encapsulation and transmission application requirements of Building Automation and Control network (BACnet) protocol messages in ZigBee network. It also proposes a kind of compatible frame structure and addressing method which is specific to wired/wireless network hybrid transmission. It discusses a design of BACnet/ZigBee wireless temperature sensor node from the point of software and hardware, and completes node software and hardware design of BACnet/ZigBee wireless temperature sensor by the embedded system Lm3s6911+, and bidirectional parsing, encapsulating, addressing, sending and receiving process between ZigBee messages and BACnet Ethernet messages are realized. This solution also can extend the current transmission and application range of BACnet messages, and provide an effective way to wired/wireless network hybrid transmission of building automation data.

Dynamic Fair Queuing (DFQ): A Novel Fair Scheduler Improving Wireless TCP over Hybrid LAN with Wired and Wireless Links

Local area network (LAN) will be a hybrid network that includes wired and wireless links together. Nonetheless, the wired hosts always take the most bandwidth and bring about the bandwidth allocation unfairness. This problem is caused by the flow control mechanism that is dominated by the round-trip time (RTT). Among the connections on a share link, the ones with shorter RTT tend to acquire ban...

Evaluating the Duration of Message Transactions in Broadcast Wired/Wireless Fieldbus Networks

Determining the response time of message transactions is one of the major concerns in the design of any distributed computer-controlled system. Such response time is mainly dependent on the medium access delay, the message length and the transmission delay. While the medium access delay in fieldbus networks has been thoroughly studied in the last few years, the transmission delay has been almos...
