This work addresses the integration of wireless nodes organized in meshed Zigbee networks with other nodes linked together over CANbus, which required a special purpose gateway. This solution allowed for transparent flows of information originating in both sensors and actuators in heavy industrial applications, encompassing different requirements regarding data rate and power source, especially in...
This paper describes a MZ communication protocol developed to solute the problem of different Programmable Controllers communication in industrial environment. The experimental result of a wireless network also is reported. It illustrates that the MZ can perform well in industrial application.
Adaptive ARQ is applied to a wireless network, altering retransmission policy according to content importance. By a video deadline-aware buffer discard policy, repeated transmission of expired packets and buffer overflow are mitigated, helping to maintain video quality. Multiple deadlines are applied according to picture type. The combined policy is demonstrated for a bluetooth piconet achieving fast...
