However, some WSN applications and higher layer protocols may strongly benefit from the possibility of supporting more traffic classes.

Thus, it enables the differentiation between real-time and best-effort traffic.

Its MAC (Medium Access Control) supports both contention-free (CFP, based on the reservation of guaranteed time-slots GTS) and contention based (CAP, ruled by CSMA/CA) access, when operating in beacon-enabled mode. The IEEE 802.15.4 is the most widespread used protocol for Wireless Sensor Networks (WSNs) and it is being used as a baseline for several higher layer protocols such as ZigBee, 6LoWPAN or Wireless HART. Finally, the article also suggests potential directions for future research in the field. Furthermore, in all these categories, research has been focused on MAC and scheduling and routing according to research area or objective in second level. As for grouping, we categorize the approaches into hard, soft, and firm real-time model.

Based on this deficiency, in this paper, we present the up-to-date research approaches and discuss the important features related to real-time communications in wireless sensor networks. In order to discuss and analyze the advantage or disadvantage of these approaches, some comprehensive survey literatures were published however they are either out of date or compiled for communication protocols on single layer. However, due to harsh networking environment around a node, many researchers usually take different approach from conventional networks. In these applications, real-time delivery is one of the important research challenges. Continuous Flow vs.Generally, various traffic requirements in wireless sensor network are mostly dependent on specific application types, that is, event-driven, continuous, and query-driven types.Meter Configurations, IDs and Data Exchange.Rules for Creating, Updating and Changing Data.Understanding the Data Exchange Starter Spreadsheet.How much time varies based on other tasks the system is handling when the reads are received. Depending on how long the gap in communication is and the endpoint type, BEACON might calculate and display estimated reads.Īfter an endpoint has communicated with BEACON, it takes time for the system to process and display the reads in the Monitor page consumption graph and on cards. If an endpoint is unable to communicate with BEACON, it will continue to try to connect to the system until it is successful. This is done to distribute network traffic and enhance system performance. For all but LTE-M endpoints, the exact hour(s) of the day that that communication occurs is set randomly for each individual endpoint. Endpoints communicate with BEACON, sending reads and other data once every 24 hours, once every six hours, or in the case of LTE-M endpoint at three configurable intervals and one fixed interval per day. Many endpoints collect reads at the top of each hour, others collect reads every 15 minutes. Communication time refers to the moment when an endpoint sends data to BEACON.Read time refers to the moment when an endpoint collects a read from a meter.The terms read time and communication time are often confused as being the same, when they are different things.
