design and manufacture of wireless sensor networks for industrial applications including process monitoring condition monitoring asset management environment health and safety ehs monitoring and power management . they are headquartered in hayward california . dust networks works with industry and standards groups such as wirelesshart ietf isa and wina to help drive the adoption of interoperable wireless sensor networking products . contents 1 company history 1.1 smart dust 1.2 timeline 2 technology 3 references 4 external links company history edit in 1997 kristofer s. j. pister a professor of electrical engineering and computer sciences at the university of california berkeley conceived of and started the smart dust project with darpa funding . smart dust edit the smart dust project 1 attempted to demonstrate that a complete sensor communication system could be made of sensors one cubic millimeter in size . this involved advances in miniaturization integration and energy management . the project focus was independent of any particular sensor and looked at both commercial and military applications including defense related sensor networks such as battlefield surveillance treaty monitoring transportation monitoring and scud hunting . virtual keyboard sensors by attaching miniature remotes on each fingernail accelerometers could then sense the orientation and motion of each fingertip and communicate this data to a computer in a wristwatch . inventory control by placing miniature sensors on each object in the inventory system product package carton pallet truck warehouse internet each component could talk to the next component in the system . this evolved into today s rfid inventory control systems . product quality monitoring temperature and humidity monitoring of perishables such as meat produce and dairy . impact vibration and temperature monitoring of consumer electronics for failure analysis and diagnostic information e.g. monitoring the vibration of bearings to detect frequency signatures that may indicate imminent failure . the project led to the founding of dust networks to provide commercial applications of the above . timeline edit july 2002

october 2007 smartmesh ia 500 family of wirelesshart standards based systems announced july 2008 launches initiative focused on the use of internet protocol ip networking in urban infrastructure building automation utility metering and other wireless sensor networking applications december 2011 dust networks is acquired by linear technology 2 technology edit wireless sensor networks attempt to increase transmission reliability and quickly adapt should the transmission fail and automatically route around failed links . this requires embedded networking intelligence that establishes maintains and utilizes redundant multi hop routing from source to destination . dust implements full mesh networks sometimes referred to as mesh to the edge which provides redundant routing to the edge of the network . in a full mesh network every device has the same routing capabilities and is able to decide where it belongs in the routing structure based on what other nodes it can communicate with its proximity to the network gateway and its traffic load . this allows for self forming and self healing . the multi chip modules used to drive these networks are divided into gateways and motes or mote modules . gateways then tie back into larger networks used to make decisions within large industrial plants oil refineries chemical plants produce facilities etc. . the company has evolved from using a proprietary protocol called tsmp time synchronized mesh protocol to wireless hart to launching an internet protocol based initiative in support of the internet engineering task force ietf
