The Optimized Link State Routing Protocol For Mobile Ad-hoc Networks
A link-state routing protocol - optimized for mobile ad-hoc networks, which can also be used on other wireless ad-hoc networks - is the Optimized Link State Routing Protocol (OLSR). OLSR is proactive, it uses Hello and Topology Control (TC) messages to discover and disseminate link state information into the mobile ad-hoc network. Using Hello messages each node discovers 2-hop neighbor information and elects a set of multipoint relays (MPRs). MPRs makes OLSR unique from other link state routing protocols. Individual nodes use the topology information to compute next hop paths regard to all nodes in the network utilising shortest hop forwarding paths.

Famous quotes containing the words link, state, mobile and/or networks:
“Because this age and the next age
Engender in the ditch,
No man can know a happy man
From any passing wretch,
If Folly link with Elegance
No man knows which is which....”
—William Butler Yeats (1865–1939)
“The truth is, the whole administration under Roosevelt was demoralized by the system of dealing directly with subordinates. It was obviated in the State Department and the War Department under [Secretary of State Elihu] Root and me [Taft was the Secretary of War], because we simply ignored the interference and went on as we chose.... The subordinates gained nothing by his assumption of authority, but it was not so in the other departments.”
—William Howard Taft (1857–1930)
“From three to six months, most babies have settled down enough to be fun but aren’t mobile enough to be getting into trouble. This is the time to pay some attention to your relationship again. Otherwise, you may spend the entire postpartum year thinking you married the wrong person and overlooking the obvious—that parenthood can create rough spots even in the smoothest marriage.”
—Anne Cassidy (20th century)
“The community and family networks which helped sustain earlier generations have become scarcer for growing numbers of young parents. Those who lack links to these traditional sources of support are hard-pressed to find other resources, given the emphasis in our society on providing treatment services, rather than preventive services and support for health maintenance and well-being.”
—Bernice Weissbourd (20th century)
