Smartdust
Smartdust is a system of many tiny microelectromechanical systems (MEMS) such as sensors, robots, or other devices, that can detect, for example, light, temperature, vibration, magnetism, or chemicals. They are usually operated on a computer network wirelessly and are distributed over some area to perform tasks, usually sensing through radio-frequency identification. Without an antenna of much greater size the range of tiny smart dust communication devices is measured in a few millimeters and they may be vulnerable to electromagnetic disablement and destruction by microwave exposure. Design and engineering The concepts for Smart Dust emerged from a workshop at RAND in 1992 and a series of DARPA ISAT studies in the mid-1990s due to the potential military applications of the technology. The work was strongly influenced by work at UCLA and the University of Michigan during that period, as well as science fiction authors Stanislaw Lem (in novels ''The Invincible'' in 1964 and '' Peace ...

TSMP
TSMP, an acronym for Time Synchronized Mesh Protocol, was developed by Dust Networks as a communications protocol for self-organizing networks of wireless devices called ''motes''. TSMP devices stay synchronized to each other and communicate in time-slots, similar to other TDM (time-division multiplexing) systems. Such deterministic communication allows the devices to stay extremely low power, as the radios only turn on for the periods of scheduled communication. The protocol is designed to operate very reliably in a noisy environment. It uses channel hopping to avoid interference -- the packets between TSMP devices get sent on different radio channels depending on time of transmission. TSMP distinguishes itself from other time-slotted mesh-based protocols, in that time-slot timing is maintained continuously and enables a network to duty-cycle on a transmitter-receiver pair-wise basis, as opposed to putting the entire network to sleep for extended periods of time (as is done in a beac ...

Multi-hop Routing
Multi-hop routing (or multihop routing) is a type of communication in radio networks in which network coverage area is larger than radio range of single nodes. Therefore, to reach some destination a node can use other nodes as relays. Since the transceiver is the major source of power consumption in a radio node and long distance transmission requires high power, in some cases multi-hop routing can be more energy efficient than single-hop routing. Typical applications of multi-hop routing: * Wireless sensor networks * Wireless mesh networks * Mobile ad hoc networks * Smart phone ad hoc network Smartphone ad hoc networks (SPANs; also ''smart phone ad hoc networks'') are wireless ad hoc networks that use smartphones. Once embedded with ad hoc networking technology, a group of smartphones in close proximity can together create an ad hoc ...s * Mobile networks with stationary multi-hop relays References {{reflist Wireless networking ...

Linear Technology
Linear Technology Corporation was an American semiconductor company that designed, manufactured and marketed high performance analog integrated circuits. Applications for the company's products included telecommunications, cellular telephones, networking products, notebook and desktop computers, video/multimedia, industrial instrumentation, automotive electronics, factory automation, process control, military and space systems. The company was founded in 1981 by Robert H. Swanson, Jr. and Robert C. Dobkin. In July 2016, Analog Devices agreed to buy Linear Technology for 14.8 billion dollars. This acquisition was finalized on March 10, 2017. The Linear name survives as the "Power by Linear" brand that is used to market the combined power management portfolios of Linear Technology and Analog Devices. Products As of August 2010, the company made over 7500 products, which they organized into seven product categories: data conversion (analog to digital converters, digital to anal ...

ISM Band
The ISM radio bands are portions of the radio spectrum reserved internationally for industrial, scientific and medical (ISM) purposes, excluding applications in telecommunications. Examples of applications for the use of radio frequency (RF) energy in these bands include radio-frequency process heating, microwave ovens, and medical diathermy machines. The powerful emissions of these devices can create electromagnetic interference and disrupt radio communication using the same frequency, so these devices are limited to certain bands of frequencies. In general, communications equipment operating in ISM bands must tolerate any interference generated by ISM applications, and users have no regulatory protection from ISM device operation in these bands. Despite the intent of the original allocations, in recent years the fastest-growing use of these bands has been for short-range, low power wireless communications systems, since these bands are often approved for such devices, which ...

IEEE 802
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LAN), personal area network (PAN), and metropolitan area networks (MAN). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently active. The IEEE 802 standards are restricted to computer networks carrying variable-size packets, unlike cell relay networks, for example, in which data is transmitted in short, uniformly sized units called cells. Isochronous signal networks, in which data is transmitted as a steady stream of octets, or groups of octets, at regular time intervals, are also outside the scope of the IEEE 802 standards. The number 802 has no significance: it was simply the next number in the sequence that the IEEE used for standards projects. ...

Institutional Venture Partners
Institutional Venture Partners (IVP) is a US-based private equity investment firm focusing on later-stage venture capital and growth equity investments. IVP is one of the oldest venture capital firms, founded in 1980. History While Reid W. Dennis was an analyst at the Fireman's Fund Insurance Company starting in 1952, he started an informal network of screened individual investors (now called angel investors). In 1974, Dennis founded Institutional Venture Associates (IVA), funded by six institutions such as American Express. Burton J. McMurtry and David Marquardt, who had been involved with IVA, left and founded Technology Venture Investors, the first investor in Microsoft. These were some of the first venture capital firms located on Sand Hill Road near Stanford University, within Silicon Valley. With his personal wealth and that of other partners, Dennis founded Institutional Venture Partners in 1980. The first IVP fund had $22 million. In a field that was generally male-domina ...
