System Framework and Protocols for Ubiquitous Computing Based Monitoring of an Oil Platform

Abstract

This book chapter proposes a system based on the WirelessHART standard for monitoring and controlling oil platforms using sensor networks. The authors propose a hierarchical distributed system where sensor nodes and process components are grouped both functionally and in terms of proximity (i.e., spatially). They harness the existing electrical powering supplies to some of the process components to enhance our network routing protocol. They also propose a component based addressing scheme. Then propose a hybrid routing protocol having proactive paths for high priority data and reactive paths for low priority that can help in load balancing and thus improving the lifetime of the sensor network. Finally, the authors discuss about methodologies for assessing the health (residual energy) of the sensor network system. Related research is discussed at appropriate points.

“…Za potrebe povezivanja izvora kontekstualnih informacija u mrežu s obzirom na gore navedene zahteve najčešće se koriste bežične senzorske mreže sa protokolima zasnovanim na IEEE 802.15.4, kao što su Zigbee (Jung, 2007), RF4CE (Yu-Ren, 2010), 6LoWPAN i ROLL (Yung-Bok, 2008), WirelessHART (Bhattacharyya, 2010), mada se koriste i bežične senzorske mreže sa protokolima zasnovanim na Bluetooth Low Energy (Gonzalez-Castano, 2005;Cano, 2006) i Z-Wave (Ghanam, 2009) Milan Bjelica -Doktorska disertacija S obzirom na raznolikost potencijalnih izvora kontekstualnih informacija u smislu protokola za povezivanje sa kontekstualnom platformom, a uslovljeno zahtevom za uspostavljanje jedinstvene (seamless) mreže, veliki broj istraživanja predlaže mehanizme za povezivanje u uslovima heterogenih mreža. Neki od predloženih mehanizama uključuju vertikalno prebacivanje sa mreže na mrežu (Balasubramaniam, 2004;McNair, 2004), kada izvor kontekstualnih informacija dinamički menja način veze u zavisnosti od mogućnosti.…”
