WirelessHART vs. Zigbee
How does the WirelessHART network protocol stack-up against the Zigbee wireless protocol? While we discuss specific differences between the two in detail in other installments, this installment of our technical discussion on the WirelessHART industrial network protocol will provide an … Continue reading
WirelessHART Slot Timing Walk Thru
In this installment of our technical discussion of the WirelessHART protocol, we present a walk through of the slot timing utilized by the data link layer. The figure below shows the slot timing of both the source and destination of … Continue reading
How does a new device join a WirelessHART network?
You install a new sensor which needs to join your WirelessHART network. How does it find its way into the network? In this installment of our technical discussion of the wireless industrial protocol, we find the network is secure, but … Continue reading
An overview of WirelessHART’s OSI layers
In this first article on the reliable network communication protocol WirelessHART, we will focus our technical discussion on the OSI layers which are implemented in the protocol and their function within the protocol. Future articles will examine each of these … Continue reading
How does WirelessHART beat the 2.4GHz Traffic?
To many of us, 2.4GHz sounds like the traffic of Interstate 10 – or whatever freeway is close to you. It is overcrowded. WiFi, cordless phones, microwave ovens, and many other wireless technologies are taking advantage of this license-free frequency … Continue reading
Advantage of TDMA in WirelessHART over CSMA
In this fourth article in our technical discussion on the WirelessHART protocol, we look at the advantage of time division multiple access (TDMA) found in WirelessHART over carrier sense multiple access (CSMA). Both methods of allowing multiple nodes to communicate … Continue reading
“This is a mesh network.” True or False?
Some network protocols claim to be mesh networks simply because their nodes can talk to one another. This article in our technical discussion on the WirelessHART protocol discusses the features of true mesh network like WirelessHART versus “fake” mesh networks. … Continue reading
Graph routing and source routing in WirelessHART
A routing protocol is the method used to determine the path a packet takes to get from its source to its destination. In this seventh article of our technical discussion of the network communication protocol WirelessHART, we examine two methods … Continue reading
Graph routing vs. AODV routing
This eighth installment in our WirelessHART protocol technical discussion examines the difference between two routing protocols: graph routing and Ad hoc On-Demand Distance Vector (AODV) routing. AODV is utilized for mobile ad hoc networks (MANETs like Zigbee) and other wireless … Continue reading
