holdum cards

A holdum cards mobile ad-hoc network is a self-configuring network of mobile routers connected by wireless links—the union of which form an arbitrary topology. The routers are free to move randomly and organise themselves arbitrarily; thus, the networks wireless topology may change rapidly and unpredictably. Such a network may operate in a standalone fashion, or may holdum cards be connected to the larger Internet.The earliest MANETs were called "packet radio" networks, and were sponsored by DARPA in the early 1970s. BBN and SRI designed, built, and experimented with these earliest systems. Experimenters included

Jerry Burchfiel, Robert Kahn, and Ray Tomlinson of holdum cards later TENEX, Internet and email fame. It is interesting to note that these early packet radio systems predated the Internet, and holdum cards indeed were part of the motivation of the original Internet Protocol suite. Later DARPA experiments included the Survivable Radio Network project, which took place in the

1980s. Another third wave of academic activity started in the mid 1990s with the advent of inexpensive 802.11 radio cards for personal computers. Current MANETs are designed primarly for military utility; examples include JTRS and NTDR.The popular IEEE 802.11 wireless protocol incorporates an ad-hoc networking system when no wireless holdum cards access points are present, although it would be considered a very low-grade ad-hoc protocol by specialists holdum cards in the field. The IEEE 802.11 system only handles traffic within a local "cloud" of wireless devices. Each node

transmits and receives data, but does not route anything between the networks systems. However, higher-level protocols holdum cards can be used to aggregate various IEEE 802.11 ad-hoc networks holdum cards into MANETs.A list of some ad-hoc network protocols can be found in the Ad hoc protocol list.The MIT Media Lab $100 laptop program hopes to develop a cheap laptop for mass distribution to developing countries for education. The laptops will use ad-hoc wireless mesh networking to develop their own communications network out of the box.See alsoWireless mesh networkExternal links Mobile Mesh Networking
